ppc: Fix modf (sNaN) for pre-POWER5+ CPU (bug 20240).

Commit a6a4395d fixed modf implementation by compiling s_modf.c and
s_modff.c with -fsignaling-nans. However these files are also included
from the pre-POWER5+ implementation, and thus these files should also
be compiled with -fsignaling-nans.

Changelog:
	[BZ #20240]
	* sysdeps/powerpc/powerpc32/power4/fpu/multiarch/Makefile
	(CFLAGS-s_modf-ppc32.c): New variable.
	(CFLAGS-s_modff-ppc32.c): Likewise.
	* sysdeps/powerpc/powerpc64/fpu/multiarch/Makefile
	(CFLAGS-s_modf-ppc64.c): Likewise.
	(CFLAGS-s_modff-ppc64.c): Likewise.
