If you simply remove graphics.h from the list of files in the
stamp-prereq target, I think you will break some other things.

I don't see how to get all the dependencies 100% correct and still
have separate Makefiles in the src and liboctave directories, and to
also handle the possibility that some values in defaults.h and
oct-conf.h may come from the environment.

I'd consider a patch, but I don't have time at the moment to try to
fix these problems.
