Merge tag 'kbuild-v5.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
Pull more Kbuild updates from Masahiro Yamada:
- raise minimum supported binutils version to 2.23
- remove old CONFIG_AS_* macros that we know binutils >= 2.23 supports
- move remaining CONFIG_AS_* tests to Kconfig from Makefile
- enable -Wtautological-compare warnings to catch more issues
- do not support GCC plugins for GCC <= 4.7
- fix various breakages of 'make xconfig'
- include the linker version used for linking the kernel into
LINUX_COMPILER, which is used for the banner, and also exposed to
/proc/version
- link lib-y objects to vmlinux forcibly when CONFIG_MODULES=y, which
allows us to remove the lib-ksyms.o workaround, and to solve the last
known issue of the LLVM linker
- add dummy tools in scripts/dummy-tools/ to enable all compiler tests
in Kconfig, which will be useful for distro maintainers
- support the single switch, LLVM=1 to use Clang and all LLVM utilities
instead of GCC and Binutils.
- support LLVM_IAS=1 to enable the integrated assembler, which is still
experimental
