New file .../.../kopensolaris-gnu/x86_64/tls.h

Copied from kopensolaris-gnu/i386 with removing INIT_SYSINFO
Backport __m128 replacement.

 (Compile x86 rtld with -mno-sse -mno-mmx)

On illumos there was one more issue:

../nptl/sysdeps/x86_64/tls.h:71:3: error: unknown type name '__m128

"sysdeps/x86_64/multiarch/strstr.c" include "nmmintrin.h",
"nmmintrin.h" includes "xmmintrin.h",
"xmmintrin.h" includes "mm_malloc.h" *before* defining __m128,
"mm_malloc.h" includes "errno.h" (only on illumos, for errno),
"include/errno.h" gets included, "include/errno.h" includes "tls.h",
"tls.h" should include "xmmintrin.h" but include guard is already
defined, so __m128 is not defined in tls.h
