[PATCH] Remove stale symlinks in ldconfig

[Jakub Jelinek]

Hi!

Pre-glibc ldconfig used to remove stale symlinks with .so. substring in
their names, current one does not.
This can result in /usr/lib and other directories cluttered with stale
symlinks after some upgrades. Many packages own the symlinks to libs and
package management removes them on upgrades, but many don't, especially
those coming from non-distro sources.
The point is when ldconfig is creating those symlinks, it should be
responsible for cleaning them up too I think.
