1279 err(3C) should be marked __NORETURN

err* and friends exit, and thus don't return.  GCC would prefer to
know this, so it doesn't warn "control reaches end of non-void
function" when that's really not the case.  I introduced such a
warning into jdtrace some months ago, and didn't spot it because it is
unfortunately not built with the shadow enabled (it seems we only
shadow compilation to intermediate objects).

Thanks,
