IIRC, I changed the way glib loads modules to use dlopen(), obviously I
missed to verify if loading modules is still working.  Anyway, since
there was this problem with .rdata sections in object files which causes
GConf to fail I need to rebuild glib2 with Charles new fixed libtool.

Thanks for this simple testcase, I'll keep this for regression testing
in future builds.
