Regular cross-configurations got around fine as they used the "host"-build libiberty, which for crosses seemed to differ from "build"-builds(!) only in that they're built at the objdir top instead of objdir/build-<hosttuple>. Crosses *could* still use the host libraries, but whatever; we're avoiding a cross-or-native-conditional now. I haven't given canadian-crosses any thought, maybe they were broken before. brgds, H-P
