Yes, Git has that functionality too. It is called "submodules". Common 
code can live and be maintained in it's own repository. Other 
repositories can than link to that repository.

I have used this often. If you clone a repository that makes use of 
submodules, all the information is already there (stored inside the 
repository).

The first time you clone such a repository, it will not automatically 
fetch the files from the submodule. You need to run (only once) the 'git 
submodule init' command. Then every time you want to update the 
"common/shared code" you run 'git submodule update'.

The Pro Git chapter explains it very well, and it is actually quite 
simple to setup and use.
