#     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
#
