- Removed multilib from gtk and gtk3 that was effectively fake (building for current ABI under if), and was making it abort due to a check that headers differed between ABIs (actually the difference was one being missing due to the if mentioned above). Seems that usage of MULTILIB_WRAPPED_HEADERS could be a workaround but it's not very correct. - Now avahi-discover is in gtk3. - Fixed bug 4622 that avahi-discover did not work.
