They are related actually. OpenNebula has always needed XMLRPC linker
flags, but this mistake was preventing it seeing them directly. By
accident it still worked though, probably because some other thing w
link to also pulls in the XMLRPC libs. When built as a dlopen'able
module though this bug was exposed.
