This patch changes the default for -mcpu=future to turn on pc-relative
addressing by default.

I have built each of the patches in turn on a little endian power8 system doing
a bootstrap and make check.  There were no regressions.  Can I check this patch
into the trunk once the previous patches are checked in?

	* config/rs6000/rs6000-cpus.def (ISA_FUTURE_MASKS_SERVER): Enable
	pc-relative support by default on 'future' systems.
