[cip-dev] [PATCH] builddeb: introduce variables for control-file customization

[henning.schild@siemens.com (Henning Schild)]

Ben,

could you please have a look at that patch. I actually need that or
something similar to build a cip-kernel for an embedded target. But i
thought i start off with an upstream patch and ask for a backport later.
