Use -mfloat128 for _Float64x tests for powerpc64le [committed]

Subject: Use -mfloat128 for _Float64x tests for powerpc64le [committed]
Authentication-results: sourceware.org; auth=none

Supporting _Float64x on powerpc64le means that tests of that type need
to use -mfloat128 just like tests of _Float128.  This patch adds the
necessary uses of that option.

Tested (compilation only) for powerpc64le with build-many-glibcs.py,
in conjunction with _Float64x support patches.  Committed.

	* sysdeps/powerpc/powerpc64le/Makefile ($(foreach
	suf,$(all-object-suffixes),$(objpfx)test-float64x%$(suf))): Add
	-mfloat128 to CFLAGS.
	($(foreach
	suf,$(all-object-suffixes),$(objpfx)test-ifloat64x%$(suf))):
	Likewise.
	(CFLAGS-libm-test-support-float64x.c): New variable.
	($(objpfx)test-float64x% $(objpfx)test-ifloat64x%): Add
	$(f128-loader-link) to gnulib-tests.
