First it would surely be better to rebuild the stubs without -O0 just to
see if it works. Is there any requirement for the stubs to be optimized? Do
they not fit otherwise?

Once we _know_ you have code that works, then you can send the patches, and
I'll gladly build you a new stub image in return :-).
