Testing narrowing functions with build-many-glibcs.py showed up a further testsuite fix needed to enable building such functions for powerpc64le: tests test-<narrower-type>-float128-<function> (and likewise for float64x) needed the same special handling for powerpc64le as test-float128-* and test-float64x-*. This patch adds that special handling. Tested with build-many-glibcs.py for powerpc64le in conjunction with the main patch adding narrowing add functions. * sysdeps/powerpc/powerpc64le/Makefile [$(subdir) = math] (f128-pairs): New variable. [$(subdir) = math] ($(foreach suf,$(all-object-suffixes),$(foreach pair,$(f128-pairs),$(objpfx)test-$(pair)%$(suf)))): Add -mfloat128 to CFLAGS. [$(subdir) = math] ($(foreach pair,$(f128-pairs),test-$(pair)%)): Also make tests add $(f128-loader-link) to gnulib-tests.
