i've hit the same in my i386 regress.  init_mock_term() tries to open
/dev/tty, but that device may not be available in all circumstances.

This seems to fix it for me, but I haven't looked closer at how the
tog regress suite works (yet!) and don't know if this breaks some
assumption not catched by regress.

(tog_io_close() will close stdin now, but I guess it's not a problem.)
