    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
