Since the kernel no longer distinguishes between i386 and
amd64, the arch variable is really x86, I think. What happens if you
install the resulting package anyway, using --force-architecture?

I don't think the logic was designed to handle this situation,
really, where you are not really cross compiling (you do not have an
alternate cross compiling tool chain), not do you have a sub arch
(since _i396.deb and _amd64.deb seem different to dpkg). At this point,
I would just force the architecture yes, dpkg, we do know better) and
leave it at that.
