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 VXX cannot
work properly).
Will commit later today (if it regstraps fine :-) )

* config/rs6000/rs6000.cc (rs6000_machine_from_flags): Don't output
"ppc" and "ppc64" based on rs6000_cpu.
