--- Comment #8 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Ah, it's more subtle than that. This isn't using the AC_CHECK_FUNCS in
libiberty/configure.ac, the header is being included as part of building
libstdc++ which doesn't explicitly check for memrchr. So HAVE_MEMRCHR is
undefined because no check was done for it by the libstdc++ build.
I think this needs a fix in libstdc++.
