That makes sense. What stat(1) actually does is call stat(2) on
/usr/lib and look up the resulting device number using devname(3).
Since it can't be found it returns "??" which is useful for ps but
not much else.
We can simplify the check and simply treat a value of "??" as
non-local and skip the reorder.
