* Implement the "dist-check" target that verifies the contents of a zipped

  tarball.
* Fix bugs in the "dist" target (a precursor to dist-check).
* Correct the implementation of the "install" targets so that they ensure
  the installation directories are created before attmpting to install
  directories in them.
* Reduce the verbosity of the output of the makefile system
* Ensure output includes the configuration whenever libraries or tools are
  built, installed, or uninstalled.
