perf symbol: Add command line support for addr2line path
Allow addr2line to be set either on the command line or via the perfconfig file. This doesn't currently work with llvm-addr2line as the addr2line code emits two things: 1) the address to decode, 2) a bogus ',' value. The expectation is the bogus value will generate: ?? ??:0 that terminates the addr2line reading. However, the output from llvm-addr2line is a single line with just the input ',' locking up the addr2line reading that is expecting a second line.

Merge tag 'perf-tools-for-v6.2-2-2022-12-22' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
Pull more perf tools updates from Arnaldo Carvalho de Melo: "perf tools fixes and improvements:
- Don't stop building perf if python setuptools isn't installed, just disable the affected perf feature.
- Remove explicit reference to python 2.x devel files, that warning is about python-devel, no matter what version, being unavailable and thus disabling the linking with libpython.
- Don't use -Werror=switch-enum when building the python support that handles libtraceevent enumerations, as there is no good way to test if some specific enum entry is available with the libtraceevent installed on the system.
- Introduce 'perf lock contention' --type-filter and --lock-filter, to filter by lock type and lock name:

- Fix splitting CC into compiler and options when checking if a option is present in clang to build the python binding, needed in systems such as yocto that set CC to, e.g.: "gcc --sysroot=/a/b/c".
- Refresh metris and events for Intel systems: alderlake. alderlake-n, bonnell, broadwell, broadwellde, broadwellx, cascadelakex, elkhartlake, goldmont, goldmontplus, haswell, haswellx, icelake, icelakex, ivybridge, ivytown, jaketown, knightslanding, meteorlake, nehalemep, nehalemex, sandybridge, sapphirerapids, silvermont, skylake, skylakex, snowridgex, tigerlake, westmereep-dp, westmereep-sp, westmereex.
- Add vendor events files (JSON) for AMD Zen 4, from sections 2.1.15.4 "Core Performance Monitor Counters", 2.1.15.5 "L3 Cache Performance Monitor Counter"s and Section 7.1 "Fabric Performance Monitor Counter (PMC) Events" in the Processor Programming Reference (PPR) for AMD Family 19h Model 11h Revision B1 processors.
This constitutes events which capture op dispatch, execution and retirement, branch prediction, L1 and L2 cache activity, TLB activity, L3 cache activity and data bandwidth for various links and interfaces in the Data Fabric.
- Also, from the same PPR are metrics taken from Section 2.1.15.2 "Performance Measurement", including pipeline utilization, which are new to Zen 4 processors and useful for finding performance bottlenecks by analyzing activity at different stages of the pipeline.
- Greatly improve the 'srcline', 'srcline_from', 'srcline_to' and 'srcfile' sort keys performance by postponing calling the external addr2line utility to the collapse phase of histogram bucketing.
- Fix 'perf test' "all PMU test" to skip parametrized events, that requires setting up and are not supported by this test.
- Update tools/ copies of kernel headers: features, disabled-features, fscrypt.h, i915_drm.h, msr-index.h, power pc syscall table and kvm.h.
- Add .DELETE_ON_ERROR special Makefile target to clean up partially updated files on error.
- Simplify the mksyscalltbl script for arm64 by avoiding to run the host compiler to create the syscall table, do it all just with the shell script.
- Further fixes to honour quiet mode (-q)"
