On powerpc64le, not all files can have the flag -mfloat128 passed as an option on the compile command, since that could conflict with other flags, such as -mno-vsx. Each file that needs the flag, gets it through a CFLAGS-filename variable on sysdeps/powerpc/powerpc64le/Makefile. The test cases tst-strtod-nan-locale and tst-wcstod-nan-locale are missing this flag. Tested for powerpc64le. * sysdeps/powerpc/powerpc64le/Makefile (CFLAGS-tst-strtod-nan-locale.c): New variable. (CFLAGS-tst-wcstod-nan-locale.c): New variable.
