    rs6000: Do not use rs6000_cpu for .machine ppc and ppc64 (PR104829)

    Fixes: 77eccbf39ed5

    rs6000.h has
      #define PROCESSOR_POWERPC   PROCESSOR_PPC604
      #define PROCESSOR_POWERPC64 PROCESSOR_RS64A
    which means that if you use things like  -mcpu=powerpc -mvsx  it will no
    longer work after my latest .machine patch.  This causes GCC build errors
    in some cases, not a good idea (even if the errors are actually
    pre-existing: using -mvsx with a machine that does not have VSX cannot
    work properly).
