Add common project Makefile for Altera projects

The project Makefiles for the Altera projects share most of their code. The
only difference is the list of project dependencies.

Create a file that has the common parts and can be included by the project
Makefiles.

This drastically reduces the size of the project Makefiles and also allows
to change the Makefile implementation without having to re-generate all
Makefiles.
