- Add CPUTYPE support for sparc64. The net result is that it's now possible

Browse Source 
to let the compiler optimize for the famility of UltraSPARC-III CPUs as the
  default already was to optimize for UltraSPARC-I/II and generating generic
  64-bit V9 is mainly for reference purposes. At least for SPARC64-V CPUs
  code optimized for UltraSPARC-I/II still is the most performant one.
  Thanks go to Michael Moll for testing SPARC64-V.
- Move a booke MACHINE_CPU bit into the right section.
