The fact that the Makefile is shipped doesn't matter... Also of course
it would work, as long as the machine that build xen have access to
internet.

If we ship OVMF sources code, we need to include its submodules, so we
need to ship openssl source code. I think I've look into removing this
build dependency, but I don't think that was possible with simple build
options.

Nothing, qemu-xen isn't a project. If you meant "what does xen.git do
regarding qemu-xen's submodules" then the answer is, we call a script
from qemu to have it export whatever it needs to build (the fact that
there are submodules are transparent to users building qemu, like xen
do).

OVMF/edk2 is a bit special, its build system doesn't know about external
source code and teaching it to do something about it is probably not
going to be simple.

So we can't treat OVMF like QEMU, regarding the build, and releases.

We probably need a script to export git-submodules in xen.git.
