#     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
#
