chicken-scheme: version 5.2.0; include compiler

* The Makefile creates two packages:
  - chicken-scheme-interpreter, same that was created
    with the previous version of the Makefile (except
    that this one includs Chicken 5.2.0);
  - chicken-scheme-full, which includes the compiler,
    debugger, profiler, and module manager.

  The -full package has some peculiarities:
  It is somewhat large, although that is not really
  an issue, since it depends on gcc, which already needs
  more than 100Mb space.
  The binaries are not stripped, because stripped binaries
  seem to break the compiler (generated objects are not
  properly linked). Since the package is large and depends
  on an even larger one, this shouldn't be a problem.
