You can specify '--reference <repo-url>' to 'git submodule update', which will make
it add that URL to the alternates of any submodule it checks out. You
can also just modify the alternates file for any submodule, since
they're regular repositories that live in .git/submodules.

There is no global alternates file as far as I know.
