I could, but I would rather not since I normally only build glibc for
MIPS and it always takes me a while to figure out the options and
settings for an x86 build. I did a build using GCC 4.9.2 for MIPS and
did not see any significant code differences with this patch (i.e. I did
not see an extra data copy on MIPS).
