I went through all the externs, and here are the unused ones in rs6000.h.

Tested by running make bootstrap on ppc64-linux/ppc32-linux.

Committed as obvious.

	* config/rs6000/rs6000.h: Remove rs6000_long_double_size_string,
	rs6000_isel, rs6000_spe, rs6000_alignment_string,
	rs6000_sched_restricted_insns_priority, rs6000_abi_string.
