[RFC][PATCH] deb target

[Wichert Akkerman]

I sent this to the listed contact for kbuild first, but Michael
Elizabeth Chastain tells me he is no longer active in kernel development
and the kbuild-devel list seems both inactive and defunct (my post
never made it to any of the list archives), so I'm reposting this
here.

For a while now I've been missing a deb target in kbuild, especially
since there is a simple rpm target. While Debian does have a tool
to create kernel packages (make-kpkg from the kernel-package package)
I felt there was a need for a simpler method build into kbuild.

The patch is imperfect and could use some changes from someone who is
more familiar with kbuild, but It Works For Me(tm). I would appreciate
any feedback people have on it.

Wichert.
