[PATCH 2/2] UBUNTU: mainline-build -- add build machinary for mainline builds

[Andy Whitcroft]

Add support for mainline builds within our tree.  From a repository with
an ubuntu kernel with a remote containing the required mainline build we
are able to build .debs for those releases.  These are packaged such that
they do not collide with our own builds.
