You're right to include c++rt0.o, because it contains __init and __fini
functions, which are called automagically when a shared library
is loaded and unloaded (the latter can happen through dlclose()).

I don't know why the global dlopen() fails, that looks like a bug. It
happens for me too when running mozilla-current on i386-current with egcs,
and I haven't looked into it any further.
