commit 7a8330c01bea0cb98654ca25e3ca5db7d48694b3
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Fri Oct 21 21:18:03 2016 +0000

    Use -fno-builtin for sqrt benchmark.
    
    This patch makes the sqrt benchmark use -fno-builtin, as already done
    for benchmarks of ffs and ffsll, so that it actually benchmarks the
    glibc function as (presumably) intended even in the presence of the
    compiler inlining sqrt.
    
    Tested for x86_64 and also used for benchmarking my ARM sqrt patch.
    
    	* benchtests/Makefile (CFLAGS-bench-sqrt.c): New variable.
