Add git-projects-dir-[include|minimal].mk

Browse source 
In the attempt to move both jw-build and the janware toplevel
Makefile from CVS to Git, add two new makefile snippets to make/*.mk:

  - projects-dir-minimal.mk

    A new toplevel-Makefile for building all projects in one go. It
    should be suitable to be downloaded from janware.com/Makefile and
    then be used to bootstrap all repos hosted on janware.com, that a
    user has access to, just like the current toplevel Makefile is.

    It is as small as possible: Little code means few assumptions on
    what the world outside of it looks like, notably jw-build. This
    is desirable, because it lives outside of version control, albeit
    for a short while, and as long as it does, there's no mechanism
    in place to keep it current.

    That said, on first use, it replaces itself with a symbolic link
    into jw-build and is then version controlled with jw-build.

  - projects-dir-include.mk

    This is essentially the existing projects-dir.mk /
    toplevel-Makefile, which it includes. It's meant as a place for
    adaptations to the next-generation implementation. This might
    prove handy to have while both implementations coexist during the
    transition phase.
