The g++ also exports symbols of implicit instantiations of templates. These
aren't part of the api and must not be accessed by any other part of
mupen64plus. We can use version-scripts to surpress these symbols without using
explicit instantiations of all templates we use.
Every time a header is changed, the user had to cleanup the whole project and
then rebuild it. It is quite easy to fix and should help a lot when working on
the project. The dependency files will be created at the first run (when
dependency tracking isn't useful anyway) and should create nearly no overhead.
