I don't think it's POSIX, but it is present on all POSIX-like systems I
know. On which system did you get the issue?

This is much less robust than the actual readlink. For example, if ->
appears in the link name, it breaks.
It would be acceptable as a fall-back if readlink is not present, but
shouldn't activate the "ls" hack by default.
