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.
