     ppc64le is its own arch treat it as such.
    
     ppc64le is ppc64 little endian, it is a completely incompatable arch
    to all other 64 bit power builds and can not be multilibbed with ppc.
    While it works okay in the default Fedora setup its because Fedora
    patches _ppc64_native_is_best to True as soon as its False you get
    unexpected results.
     This patch covers things in both setups and makes it clear how it
    works.
