This was used by --enable-omitfp, and the bulk of it was removed in this
commit:

There is a configure test for assembler support for -mtune=i686. This
option was added in binutils 2.18 so the test is obsolete; this patch
removes it.
Tested for x86 (testsuite, and that installed shared libraries are
unchanged by the patch).
* sysdeps/i386/configure.ac (libc_cv_as_i686): Remove configure
test.
* sysdeps/i386/configure: Regenerated.
* sysdeps/i386/i686/Makefile [$(config-asflags-i686) = yes]: Make
code unconditional.

Since _dl_x86_cpu_features is always available, we can use x86-64
cacheinfo.c and sysconf.c for both i386 and x86-64.

[$(subdir) == string] (sysdep_routines): Moved to ...

The testcase stdlib/tst-makecontext fails on i686 because
_Unwind_Backtrace from libgcc produces a segmentation fault if it was
called within a context created by makecontext. See Bug 18635.
ChangeLog:
* sysdeps/i386/i686/Makefile (test-xfail-tst-makecontext):
New variable.

Without HP_TIMING_ACCUM, dl_hp_timing_overhead is write-only.
If we remove it, there's no point in HP_TIMING_DIFF_INIT either.

This patch adds multiarch support when configured for i686. I modified
some x86-64 functions to support 32bit. I will contribute 32bit SSE string
and memory functions later.

required.
