So I am still trying to understand WTF the glib design is supposed to
be. What I am guessing at the moment is that an application is supposed
to link against libglibthread if it wants to create threads. So the fix
for glib in this case would be to not use pthread_create as strong
symbol and/or link against a library just providing it as weak AND
require libglibthread to link against libpthread.
