[PATCH] Change PPC64 Linux default to POWER8.

[David Edelsohn]

This patch updates the default processor tuning to POWER8 for any
PPC64 Linux target, not only little endian (ELFv2).

Any objection?

Thanks, David

* config/rs6000/linux64.h (PROCESSOR_DEFAULT): Change to PROCESSOR_POWER8.
(PROCESSOR_DEFAULT64): Same.
