JACK and unclean upstream tarballs

[Felipe Sateler]

Upstream apparently doesn't run make distclean on their tarballs. Running 
debian/rules clean leaves a dirty git repo, which makes it annoying for 
testing stuff. 

How do you propose to handle this? We can either add a .gitignore file, or just 
remove said files from the master branch. I prefer the second one, since then 
the starting point is guaranteed to be clean. Having a clean start point also 
ensures that bugs like 527335 don't happen. Also possible is to ask upstream 
to just run make distclean, but they probably go out of their way for a reason 
when building the tarballs.

What do you think?
