I don't have time to think about this much, but it seems to me that
keeping all the symlinks up to date requires a time-consuming walk of
the entire ports tree. However, I'm not sure package builds or index
builds need to know anything about this, since they can just ignore
the symlinks (which represent a duplicate path to the same directory)
and proceed as now with how they do things.
