    kbuild: introduce subdir-ccflags-y · 720097d8

    Following patch introduce support for setting options
    to gcc that has effect for current directory and all
    subdirectories.
    
    The typical use case are an architecture or a subsystem that
    decide to cover all files with -Werror.
    Today alpha, mips and sparc uses -Werror in almost all their
    Makefile- with subdir-ccflag-y it is now simpler to do so
    as only the top-level directories needs to be covered.
    
    Likewise if we decide to cover a full subsystem such
    as net/ with -Werror this is done by adding a single
    line to net/Makefile.
