Adding binary files to build

[Gaute Hvoslef Kvalnes <gaute@verdsveven.com>]

I'm building OpenOffice using the Debian 1.0.1-4 packages. I've added (huge) 
patches containing Norwegian Bokmål translations to the debian/patches 
directory, and this works great. However, I need to add some binary files as 
well (help files, templates, etc.), which are not included in the upstream 
1.0.1 tarball.

Do the build environment offer a clean way to add those binary files after 
the main tarball is extracted, or do I have to hack the build scripts to make 
it work?
