powerpc64: apply -mabi=ibmlongdouble to special files Some of these files depend on the avoidance of using the various register sets of POWER. When enabling the IEEE 128 long double, we must be sure to disable this ABI as some compilers will refuse to compile if -mno-vsx and -mabi=ieeelongdouble are both present.

powerpc: Fix strstr/power7 build This patch fixes the strstr build with --disable-multi-arch option. The optimization calls the __strstr_ppc symbol, which always build for multiarch config but not if it is disable. This patch fixes it by adding the default C implementation object with the expected symbol name. * sysdeps/powerpc/powerpc64/power7/Makefile [$(subdir) = string] (sysdep_routines): Add strstr-ppc64. * sysdeps/powerpc/powerpc64/power7/strstr-ppc64.c: New file. 2015-07-28 18:34:25 +00:00			`sysdep_routines += strstr-ppc64`
