we have no tarballs anymore, it's submodules all the way down.

Either don't do the initial "git submodule update --init" yourself and
let the makefile handle that or add the "--recursive" flag..

But a fresh
# git clone git://git.proxmox.com/git/pve-kernel.git
# make

works just fine, just retried here.

your zfs submodule is not correctly checked out, it uses a submodule itself
the 
# git submodule update --init --recursive submodules/zfsonlinux
command normally takes care of that, but as you manually did one
without the --recursive flag the 
# test -f "submodules/zfsonlinux/Makefile" || git submodule update --init --recursive submodules/zfsonlinux
makefield command doesn't execute any more as the first
condition is already true.

Try
# git submodule update --init --recursive submodules/zfsonlinux
to fiy this up without a fresh clone or other things
