That reminded me that I have this patch lying around, which I'd been
meaning to put forward.
The motivation behind this was that libtool currently doesn't know about
systems where ldconfig has extra default trusted directories (such as
/usr/lib64) so libtool sets an rpath for libraries installed in these
directories, which is against the policies of most Linux distros, and
fixing this currently requires hackery in packaging scripts. But it
nicely solves this issue too.
Patch is against the 1.5 branch, because that's where I was trying
this out, but if you think this approach is suitable for inclusion, I'm
happy to update it for HEAD and try to provide a suitable ChangeLog
entry.
