readlink is required by Single Unix Spec v2 (1997), which is what we've
been treating as our baseline expectation for Unix-oid platforms for
awhile now. Given that we dealt with the Windows side already, I don't
see a problem with making this assumption. At worst we'd end up needing
a couple more emulations in src/port, since surely there's *some* way to
do it on any platform with symlinks.
