    Subject[PATCH] ix86: improve determination of X86_MINIMUM_CPU_FAMILY
    This was quite a bit off: While I never build for anything older than
    i686 (other than for specifically trying certain things out), one of my
    32-bit configs (tailor made for a VIA system) ended up having this set
    to 4. Others, customized for more mainstream systems, had this set to 5.

    Once at it, also drop the unnecessary dependencies on X86_32 - that
    symbol being the inverse of X86_64, and Kconfig default determination
    working by a first match algorithm, X86_64 being dealt with in the very
    first selection makes it unnecessary to have that dependency in all
    subsequent default selections.
