re PR target/78056 (build failure on Power7)

gcc/ChangeLog:

2016-10-26  Kelvin Nilsen  <kelvin@gcc.gnu.org>

	PR target/78056
	* config/rs6000/rs6000.c (spe_init_builtins): Modify loops to not
	define builtin functions from the bdesc_spe_predicates or
	bdesc_spe_evsel arrays if the builtin mask is not compatible with
	the current compiler configuration.
	(paired_init_builtins): Modify loop to not define define builtin
	functions from the bdesc_paried_preds array if the builtin mask is
	not compatible with the current compiler configuration.
	(altivec_init_builtins): Modify loops to not define the
	__builtin_altivec_stxvl function nor the builtin functions from
	the bdesc_dst or bdesc_altivec_preds, or bdesc_abs arrays if the
	builtin mask is not compatible with the current compiler
	configuration.
