Subject: [PATCH] Add option to disable unit tests

The unittests require C++, while the rest of the library does not, so
this commit implements a --{enable,disable}-unittests option to
selectively enable the build of the unit tests. When not provided, the
option defaults to yes so that the existing behavior is preserved.

Based on initial work by Bernd Kuhls.
