I'm not sure my patches will address this specific case since looking
at the email trail the path was hard-coded in the library.  My patches
delt with the default search path which is already unique in this
case (lib32).  It also modified the search paths for LD_LIBRARY_PATH
and LD_PRELOAD.

So this is probably another case to look at.  Dealing with this
might be good to do via an extension libmap.conf.  I haven't
had a chance to look at doing that to make things more flexible.
