Yeah, that was the missing point. turned out that just creating them
in the corresponding hook rule was trivial. Not nice, but i can
live with that.

Uuuh, i didn't expect that.

Could it be that it's magically doing that on its own ?
I wonder, because I successfully built it via pbuilder/debuild (but not
tested) yet - with my drm queue applied - and the new symbols appeared.
If it wouldn't work in one pass, then at least the backends should be
missing (if it compiles at all).

I dont think the tarball should contain any autogenerated stuff.
That brings the risk that not everything's regenerated, if some patches
applied (especially ugly for distros/packaging). Fortunately it's not
in the git repo (otherwise git-buildpackage would break).
