This will ensure that a 'make compile' on a freshly-cloned repo
will first clone all the deps to ensure a successful build

We used to rely on out-of-tree git clones to be prepared by the user.
This commit changes the system to make sure we clone all git repos
we depend upon into the 'deps' folder, and then setup the symlinks
to that folder. As a result, we should be able to support
self-contained builds using the makefiles in this repo.
