Merge tag 'kbuild-v5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild

Pull Kbuild updates from Masahiro Yamada:

- add modpost warn exported symbols marked as 'static' because 'static'
and EXPORT_SYMBOL is an odd combination

- break the build early if gold linker is used

- optimize the Bison rule to produce .c and .h files by a single
pattern rule

- handle PREEMPT_RT in the module vermagic and UTS_VERSION

- warn CONFIG options leaked to the user-space except existing ones

- make single targets work properly

- rebuild modules when module linker scripts are updated

- split the module final link stage into scripts/Makefile.modfinal

- fix the missed error code in merge_config.sh

- improve the error message displayed on the attempt of the O= build in
unclean source tree

- remove 'clean-dirs' syntax

- disable -Wimplicit-fallthrough warning for Clang

- add CONFIG_CC_OPTIMIZE_FOR_SIZE_O3 for ARC

- remove ARCH_{CPP,A,C}FLAGS variables

- add $(BASH) to run bash scripts

- change *CFLAGS_<basetarget>.o to take the relative path to $(obj)
instead of the basename

- stop suppressing Clang's -Wunused-function warnings when W=1

- fix linux/export.h to avoid genksyms calculating CRC of trimmed
exported symbols

- misc cleanups

kbuild: rename KBUILD_ENABLE_EXTRA_GCC_CHECKS to KBUILD_EXTRA_WARN

KBUILD_ENABLE_EXTRA_GCC_CHECKS started as a switch to add extra warning
options for GCC, but now it is a historical misnomer since we use it
also for Clang, DTC, and even kernel-doc.

Rename it to more sensible, shorter KBUILD_EXTRA_WARN.

For the backward compatibility, KBUILD_ENABLE_EXTRA_GCC_CHECKS is still
supported (but not advertised in the documentation).

I also fixed up 'make help', and updated the documentation.

kbuild: make bison create C file and header in a single pattern rule

We generally expect bison to create not only a C file, but also a
header, which will be included from the lexer.

Currently, Kbuild generates them in separate rules. So, for instance,
when building Kconfig, you will notice bison is invoked twice:

HOSTCC scripts/kconfig/conf.o
HOSTCC scripts/kconfig/confdata.o
HOSTCC scripts/kconfig/expr.o
LEX scripts/kconfig/lexer.lex.c
YACC scripts/kconfig/parser.tab.h
HOSTCC scripts/kconfig/lexer.lex.o
YACC scripts/kconfig/parser.tab.c
HOSTCC scripts/kconfig/parser.tab.o
HOSTCC scripts/kconfig/preprocess.o
HOSTCC scripts/kconfig/symbol.o
HOSTLD scripts/kconfig/conf

Make handles such cases nicely in pattern rules [1]. Merge the two
rules so that one invokcation of bison can generate both of them.

HOSTCC scripts/kconfig/conf.o
HOSTCC scripts/kconfig/confdata.o
HOSTCC scripts/kconfig/expr.o
LEX scripts/kconfig/lexer.lex.c
YACC scripts/kconfig/parser.tab.[ch]
HOSTCC scripts/kconfig/lexer.lex.o
HOSTCC scripts/kconfig/parser.tab.o
HOSTCC scripts/kconfig/preprocess.o
HOSTCC scripts/kconfig/symbol.o
HOSTLD scripts/kconfig/conf

[1] Pattern rule

GNU Make manual says:
"Pattern rules may have more than one target. Unlike normal rules,
this does not act as many different rules with the same prerequisites
and recipe. If a pattern rule has multiple targets, make knows that
the rule's recipe is responsible for making all of the targets. The
recipe is executed only once to make all the targets. When searching
for a pattern rule to match a target, the target patterns of a rule
other than the one that matches the target in need of a rule are
incidental: make worries only about giving a recipe and prerequisites
to the file presently in question. However, when this file's recipe is
run, the other targets are marked as having been updated themselves."
