A big job for someone else. I'm trying not to become a full-time dejagnu 
hacker, although it certainly feels like it from the last week. I agree it 
should be done: there should be a dg-like framework 
for using libtool with dejagnu that works correctly with sim and sid. 

Personally, I think that after some kind of sense is made WRT cross 
compiler building/installing, where binaries are pre-installed into a 
specified location, much of the currently twisted cross machinery can be greatly 
simplified. This includes a sane testing framework.

This is now checked in. John, does this help reslove some of the testing 
difficulties on HPUX?
