Is readlink already being replaced due to other bugs?  (I guess I need
to look more closely at your logs.)  If so, then I think the replacement
should work around this.  If not, I'm perfectly fine relaxing the test
(there's already a number of places where we can't guarantee the same
errno as required by POSIX without lots of bloat; as long as a
reasonable error happens, it's generally okay for a looser test).
