    We also have archs where we add options to gcc that may
    impact for example -fno-stack-protector.
    We had a bug in x86 in this area for a while.

    So the only sane thing is to only add the most generic options to
    KBUILD_CFLAGS before we include the arch specific part.
    And we can then add the conditional options later - like
    the KBUILD_CFLAGS += $(call cc-option, -fno-stack-protector)
    in this case.

    We learned a few lessons in this area over time as your
    history digging also showed.
