Michal please care to queue previous v2 patch with
Tested-by: Tzafrir Cohen <tzafrir.cohen@xorcom.com>
to kope with that cross building regression since
the linux headers got added to deb-pkg target.

In any case that would be a follow up, but I'm not fond of that perl/dpkg
magic plus supporting DEB_ variables. I think for linux it is preferable
to have it based on UTS_MACHINE. Thus I think your testcases aren't valid,
and also you neglected the following one:
make KBUILD_DEBARCH=i386 deb-pkg # i386 userland with amd64 linux
Best.
