Remove assembler -mtune=i686 configure test.
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 This option was added in binutils 2.18 so the test is obsolete; this patch removes it.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.
