So, for each subproject of a parent project, you want to record branch, 
version (commit ID), and directory location. Not quite as easy to do in 
a makefile but do-able.

I've been playing with this kind of subprojects a little bit.

My current approach is like this:

 * create a .gitmodules file which lists all the directories
   which contain a submodule.
 * the .git/refs/heads directory of the submodule gets stored in
   .gitmodule/<modulename> inside the parent project

Taking this a step further, you could make subproject/.git/refs/heads a 
symbolic link to .git/refs/heads/subproject, with the benefit that fsck 
Just Works.

Nevertheless, you have to take care of the fact that you need to commit 
the state of the root project just after committing to any subproject.
