    commit a86fe353 written by me.
    
    W=... provides extra gcc checks.
    
    Having such code in scripts/Makefile.build results in the same flags
    being added to KBUILD_CFLAGS multiple times becuase
    scripts/Makefile.build is invoked every time Kbuild descends into
    the subdirectories.
    
    Since the top Makefile is already too cluttered, this commit moves
    all of extra gcc check stuff to a new file scripts/Makefile.extrawarn,
    which is included from the top Makefile.
