[PATCH 1/3] powerpc: Add -mfloat128 to tst-strtod-nan-locale testcase

["Gabriel F. T. Gomes" <gabriel at inconstante dot eti dot br>]

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.
