Hmm, would that option work everywhere, though? Or would we have to
wire up configury to detect which flag to use? If so, what would it
look like.

If you mean the one generated by gettext.m4/uninstalled-config.sh, it is
utilized today:
LIBS = @LIBS@ libcommon.a $(CPPLIB) $(LIBINTL) $(LIBICONV) $(LIBBACKTRACE) \
$(LIBIBERTY) $(LIBDECNUMBER) $(HOST_LIBS)
(from gcc/Makefile.in)

David, I'll leave that decision up to you.
