+On top of this patch we include a few more redirecting versions of
+the rtld-* routines in multiarch, this is needed because of the
+sysd-rules which try to build from multiarch first and will even
+use memset.S from multiarch to buidl rtld-memset.os, which results
+in SSE register usage in rtld which we can't allow because of
+lazy binding (though in some cases we use RTLD_PREPARE_FOREIGN_CALL
+and others to wrap such calls).
