This is my first attempt at building inn2 two times from the same source
with no duplication of debian/rules and of the debhelper config files.
I do not like much the src_files stuff, but it's shorter than embedding
lndir in the package like I did for udev and udev-udeb.

Please let me know if you have ideas about how to make this simpler
and/or more elegant.

The complete package will be available in a few hours at
http://www.bofh.it/~md/debian/ (please test if it you can, I do not have
yet a news server running unstable).
