Don't disable SSE in x86-64 ld.so
Since x86-64 ld.so preserves vector registers now, we can use SSE in x86-64 ld.so. We should run tst-ld-sse-use.sh only on i386. * sysdeps/x86/Makefile [$(subdir) == elf] (CFLAGS-.os, tests-special, $(objpfx)tst-ld-sse-use.out): Moved to ... * sysdeps/i386/Makefile [$(subdir) == elf] (CFLAGS-.os, tests-special, $(objpfx)tst-ld-sse-use.out): Here. Update comments. * sysdeps/x86_64/Makefile [$(subdir) == elf] (CFLAGS-.os): Add -mno-mmx for $(all-rtld-routines). * sysdeps/x86/tst-ld-sse-use.sh: Moved to ... * sysdeps/i386/tst-ld-sse-use.sh: Here. Replace x86-64 with i386.
