    x86: unify CPU_TYPE for legacy and geode
    
    According to some reports, -march=pentium-mmx is a better choice for
    older Geode CPUs than -march=geode anyway.
    
    Bump the minimum architecture of the legacy target from i486 to
    pentium-mmx. Anything older is not worth supporting anyway.
