A symlink is entirely defined by the name of the link and what it points
at.  Calculating 160 bytes of sha512 on top of that would be overkill.

So, why doesn't pkg record symlink name and target in the pkg metadata,
instead adding the symlink as a separate file in the tar archive?
Hmmm....  good question.  We need to fix that.   Issue #804 created.
