For simple cases - can we get away with tiny'ish freestanding test programs that invoke the tested syscalls so that we don't have to pull a new cross-compilation setup out of thin air just for that? Testing something like lwp-related calls probably requires a real linux libpthread anyway, not a gum-and-toothpicks effigy. -uwe
