    I think the fundamental problem here is that "make randconfig" is
    allowed to retain *any* information from the previous .config; the same
    is true for "make all*config", "make defconfig", etc. These by
    definition should blast the current configuration away.

    Now, "make randconfig" should ideally be able to generate either a 32-
    or a 64-bit configuration (which would have to be done correctly), but
    if ARCH is set we need to honor it.
