commit b7d09f0d63a5d6705b5e275b8e3c855210b173a0

    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    option was added in binutils 2.18 so the test is obsolete; this patch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.
