I know of no way to do this in the case of shared libraries.  When 
linking shared libraries, the linker *cannot* resolve any references to 
other shared libraries other than list them in the .dynamic section with 
some sort of tag such as DT_NEEDED.  Please explain to me how the linker 
can prune the shared library list at link time.

Sorry that this has veered off into a dead-end.  I promise to cut the 
mailing list from any further discussions on this dead-end thread.
