> rs6000_builtin_decl should be working correctly.
Indeed,
I suspect it is because we patch the builtin names to append $LDBL128 for the
case that we have 128bit long doubles. However, I've not had a chance to
investigate why that patching process does not result in a correctly emitted
builtin (or maybe the target needs to get to opportunity to do so in lto).
