Subject: [PATCH] A file can also be a link, so check not only for a file, but
 also for a link in the delete-old and check-old targets.

We don't install a lib (libXY.so.Z) as a link, but an user may have created
something like this. This is dangerous if this link points to a different
version of the lib. So check for a link also in the *-lib targets (an
annoyed user which absolutely wants this redirection of a lib should use
libmap.conf instead of a link).

A directory can also be a link, but in this case just echo a message to
remove it by hand.
