I now think this should be reverted. Initializing and updating the
submodules every build causes it to download all the submodules every
build. That's hardly optimal, and sometimes the submodules aren't even
needed for building.

Rather, I think we need to have the PKGBUILD handle submodules
manually. So, revert this patch and write PKGBUILDs like this:

md5sums=(SKIP SKIP SKIP)

build() {
  cd foo

  git submodule init
  git config submodule.qux/bar.url "$srcdir/foo-module-bar"
  git config submodule.qux/baz.url "$srcdir/foo-module-baz"
  git submodule update


Here, foo is our top-level repo, and foo-module-ba[rz] are the
submodules used. The names of the submodules in the foo repo are
"qux/bar" and "qux/baz". The PKGBUILD initializes the submodules
(copying the config from .gitmodules to the local .git/config), then
sets the clone URL for the submodules to the clones we already have.
The update then clones from there.

Does somepony have an idea how to automate this? In the meantime,
please revert the patch so submodules can be handled manually, as
