--- Comment #1 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
I think _HAVE_STRING_ARCH_mempcpy is expected to be defined only when
mempcpy is an alternative entry point to memcpy, as otherwise using
mempcpy will increase cache usage and so inlining the expansion in terms
of memcpy is expected to be more efficient.
