thanks that's great.


fjp had back a year ago asked for a bindeb-pkg once we add more things
to deb-pkg. I had submitted linux-libc-dev built out of deb-pkg
http://marc.info/?l=linux-kbuild&m=125737390700914&w=2

It's an orthogonal issue, but just to clear it up.

could move up to the other mkdir calls.
