tools build: Add tools tree support for 'make -s'

When doing a kernel build with 'make -s', everything is silenced except
the objtool build. That's because the tools tree support for silent
builds is some combination of missing and broken.

Three changes are needed to fix it:

- Makefile: propagate '-s' to the sub-make's MAKEFLAGS variable so the
tools Makefiles can see it.

- tools/scripts/Makefile.include: fix the tools Makefiles' ability to
recognize '-s'. The MAKE_VERSION and MAKEFLAGS checks are copied from
the top-level Makefile. This silences the "DESCEND objtool" message.

- tools/build/Makefile.build: add support to the tools Build files for
recognizing '-s'. Again the MAKE_VERSION and MAKEFLAGS checks are
copied from the top-level Makefile. This silences all the object
compile/link messages.

Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull perf updates from Ingo Molnar:
"Kernel side changes:

- Add Intel RAPL energy counter support (Stephane Eranian)
- Clean up uprobes (Oleg Nesterov)
- Optimize ring-buffer writes (Peter Zijlstra)

Tooling side changes, user visible:

- 'perf diff':
- Add column colouring improvements (Ramkumar Ramachandra)

- 'perf kvm':
- Add guest related improvements, including allowing to specify a
directory with guest specific /proc information (Dongsheng Yang)
- Add shell completion support (Ramkumar Ramachandra)
- Add '-v' option (Dongsheng Yang)
- Support --guestmount (Dongsheng Yang)

- 'perf probe':
- Support showing source code, asking for variables to be collected
at probe time and other 'perf probe' operations that use DWARF
information.

This supports only binaries with debugging information at this
time, detached debuginfo (aka debuginfo packages) support should
come in later patches (Masami Hiramatsu)

- 'perf record':
- Rename --no-delay option to --no-buffering, better reflecting its
purpose and freeing up '--delay' to take the place of
'--initial-delay', so that 'record' and 'stat' are consistent
(Arnaldo Carvalho de Melo)
- Default the -t/--thread option to no inheritance (Adrian Hunter)
- Make per-cpu mmaps the default (Adrian Hunter)

- 'perf report':
- Improve callchain processing performance (Frederic Weisbecker)
- Retain bfd reference to lookup source line numbers, greatly
optimizing, among other use cases, 'perf report -s srcline'
(Adrian Hunter)
- Improve callchain processing performance even more (Namhyung Kim)
- Add a perf.data file header window in the 'perf report' TUI,
associated with the 'i' hotkey, providing a counterpart to the
--header option in the stdio UI (Namhyung Kim)

- 'perf script':
- Add an option in 'perf script' to print the source line number
(Adrian Hunter)
- Add --header/--header-only options to 'script' and 'report', the
default is not tho show the header info, but as this has been the
default for some time, leave a single line explaining how to
obtain that information (Jiri Olsa)
- Add options to show comm, fork, exit and mmap PERF_RECORD_ events
(Namhyung Kim)
- Print callchains and symbols if they exist (David Ahern)

- 'perf timechart'
- Add backtrace support to CPU info
- Print pid along the name
- Add support for CPU topology
- Add new option --highlight'ing threads, be it by name or, if a
numeric value is provided, that run more than given duration
(Stanislav Fomichev)

- 'perf top':
- Make 'perf top -g' refer to callchains, for consistency with
other tools (David Ahern)

- 'perf trace':
- Handle old kernels where the "raw_syscalls" tracepoints were
called plain "syscalls" (David Ahern)
- Remove thread summary coloring, by Pekka Enberg.
- Honour -m option in 'trace', the tool was offering the option to
set the mmap size, but wasn't using it when doing the actual mmap
on the events file descriptors (Jiri Olsa)

- generic:
- Backport libtraceevent plugin support (trace-cmd repository, with
plugins for jbd2, hrtimer, kmem, kvm, mac80211, sched_switch,
function, xen, scsi, cfg80211 (Jiri Olsa)
- Print session information only if --stdio is given (Namhyung Kim)

Tooling side changes, developer visible (plumbing):

- Improve 'perf probe' exit path, release resources (Masami
Hiramatsu)
- Improve libtraceevent plugins exit path, allowing the registering
of an unregister handler to be called at exit time (Namhyung Kim)
- Add an alias to the build test makefile (make -C tools/perf
build-test) (Namhyung Kim)
- Get rid of die() and friends (good riddance!) in libtraceevent
(Namhyung Kim)
- Fix cross build problems related to pkgconfig and CROSS_COMPILE not
being propagated to the feature tests, leading to features being
tested in the host and then being enabled on the target (Mark
Rutland)
- Improve forked workload error reporting by sending the errno in the
signal data queueing integer field, using sigqueue and by doing the
signal setup in the evlist methods, removing open coded equivalents
in various tools (Arnaldo Carvalho de Melo)
- Do more auto exit cleanup chores in the 'evlist' destructor, so
that the tools don't have to all do that sequence (Arnaldo Carvalho
de Melo)
- Pack 'struct perf_session_env' and 'struct trace' (Arnaldo Carvalho
de Melo)
- Add test for building detached source tarballs (Arnaldo Carvalho de
Melo)
- Move some header files (tools/perf/ to tools/include/ to make them
available to other tools/ dwelling codebases (Namhyung Kim)
- Move logic to warn about kptr_restrict'ed kernels to separate
function in 'report' (Arnaldo Carvalho de Melo)
- Move hist browser selection code to separate function (Arnaldo
Carvalho de Melo)
- Move histogram entries collapsing to separate function (Arnaldo
Carvalho de Melo)
- Introduce evlist__for_each() & friends (Arnaldo Carvalho de Melo)
- Automate setup of FEATURE_CHECK_(C|LD)FLAGS-all variables (Jiri
Olsa)
- Move arch setup into seprate Makefile (Jiri Olsa)
- Make libtraceevent install target quieter (Jiri Olsa)
- Make tests/make output more compact (Jiri Olsa)
- Ignore generated files in feature-checks (Chunwei Chen)
- Introduce pevent_filter_strerror() in libtraceevent, similar in
purpose to libc's strerror() function (Namhyung Kim)
- Use perf_data_file methods to write output file in 'record' and
'inject' (Jiri Olsa)
- Use pr_*() functions where applicable in 'report' (Namhyumg Kim)
- Add 'machine' 'addr_location' struct to have full picture (machine,
thread, map, symbol, addr) for a (partially) resolved address,
reducing function signatures (Arnaldo Carvalho de Melo)
- Reduce code duplication in the histogram entry creation/insertion
(Arnaldo Carvalho de Melo)
- Auto allocate annotation histogram data structures (Arnaldo
Carvalho de Melo)
- No need to test against NULL before calling free, also set freed
memory in struct pointers to NULL, to help fixing use after free
bugs (Arnaldo Carvalho de Melo)
- Rename some struct DSO binary_type related members and methods, to
clarify its purpose and need for differentiation (symtab_type, ie
one is about the files .text, CFI, etc, i.e. its binary contents,
and the other is about where the symbol table came from (Arnaldo
Carvalho de Melo)
- Convert to new topic libraries, starting with an API one (sysfs,
debugfs, etc), renaming liblk in the process (Borislav Petkov)
- Get rid of some more panic() like error handling in libtraceevent.
(Namhyung Kim)
- Get rid of panic() like calls in libtraceevent (Namyung Kim)
- Start carving out symbol parsing routines (perf, just moving
routines to topic files in tools/lib/symbol/, tools that want to
use it need to integrate it directly, ie no
tools/lib/symbol/Makefile is provided (Arnaldo Carvalho de Melo)
- Assorted refactoring patches, moving code around and adding utility
evlist methods that will be used in the IPT patchset (Adrian
Hunter)
- Assorted mmap_pages handling fixes (Adrian Hunter)
- Several man pages typo fixes (Dongsheng Yang)
- Get rid of several die() calls in libtraceevent (Namhyung Kim)
- Use basename() in a more robust way, to avoid problems related to
different system library implementations for that function
(Stephane Eranian)
- Remove open coded management of short_name_allocated member (Adrian
Hunter)
- Several cleanups in the "dso" methods, constifying some parameters
and renaming some fields to clarify its purpose (Arnaldo Carvalho
de Melo)
- Add per-feature check flags, fixing libunwind related build
problems on some architectures (Jean Pihet)
- Do not disable source line lookup just because of one failure.
(Adrian Hunter)
- Several 'perf kvm' man page corrections (Dongsheng Yang)
- Correct the message in feature-libnuma checking, swowing the right
devel package names for various distros (Dongsheng Yang)
- Polish 'readn()' function and introduce its counterpart,
'writen()' (Jiri Olsa)
- Start moving timechart state from global variables to a 'perf_tool'
derived 'timechart' struct (Arnaldo Carvalho de Melo)
