Remove the -X option from SMALL shells (as used on boot floppies,
some other install media, mini-roots, etc.) It is unlikely that such a shell will be used for much script debugging (and the old -x still exists of course) and it adds a little bloat, so, zap... The ancient unused (unrelated) xioctl() function is gone as well (from all shells).
