examplesbparts makefile rather than use the simavr
makefile, allowing installation of simavr (alone) on
machines without a working glut.

Fix RELEASE=1 option to additionally specify rpath (not
just rpath-link) if simavr will be installed in a special
directory.

Add detection and use of librt when available (e.g.,
RHEL 6.9).
