This should simplify the input of the derivation builder significantly and of
course we don't need to rely on mawercer.de to supply the needed files. Also,
the derivation name doesn't include "-cvs" anymore, as we're building from the
release tarball.
In addition, we don't need the patch anymore, as it was so simple that it could
be done easily with sed.
