Just to let you know that this would be my prefered solution, I dont think
performance would suffer too much, as most monster software I have seen is
architectured around many shared libs, the main program being small in
comparison, we would also regain some of the lost performance in the shared
libs thanks to the -Bsymbolic speedup.
