    kbuild: do not pick up CFLAGS from the environment · 69ee0b35

    Too many people have CFLAGS set to support building userspace.
    And now Kbuild picks up CFLAGS this caused troubles.
    
    Although people should realise that setting CFLAGS has
    a 'global' effect the impact on the kernel build is a suprise.
    So change kbuild to pick up value from KCFLAGS that is
    much less used.
    
    When kbuild pick up a value it will warn like this:
    Makefile:544: "WARNING: Appending $KCFLAGS (-O3) from environment to kernel $CFLAGS"
