I assumed it was dkms because that's the top of the chain, and when
unsetting it there it wasn't defined anymore down the stack up to the
makefile. This is in a very basic sid chroot with nothing but build
dependencies installed, and tested by installing nvidia-kernel-dkms and
calling dkms install.

Any idea what else could be setting that var?

Note that I haven't tested running with this yet, only the module build in
all archs. I'll do that tonight.

Unfortunately as far as I can see all tests individually redirect to
dev/null, so we'd have to patch every single one of them :-(

Kind regards,
