Merge tag 'kbuild-v4.18-2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
Pull more Kbuild updates from Masahiro Yamada:
- fix some bugs introduced by the recent Kconfig syntax extension
- add some symbols about compiler information in Kconfig, such as
CC_IS_GCC, CC_IS_CLANG, GCC_VERSION, etc.
- test compiler capability for the stack protector in Kconfig, and
clean-up Makefile
- test compiler capability for GCC-plugins in Kconfig, and clean-up
Makefile
- allow to enable GCC-plugins for COMPILE_TEST
- test compiler capability for KCOV in Kconfig and correct dependency
- remove auto-detect mode of the GCOV format, which is now more nicely
handled in Kconfig
- test compiler capability for mprofile-kernel on PowerPC, and clean-up
Makefile
- misc cleanups
