[mesa-users] parallel make

[Michael Zingale]

you need to have your dependencies specified correctly.  We have our
Makefile build the dependency list first and then it is always up to date.
Then make can do things in parallel as needed.  I wrote a simple F90
dependency script a while back:

This is similar in spirit to the one that is wired into the Makefile for
our code (Maestro).
