From: Martin Wilck <mwilck@xxxxxxxx>
The unit tests use a lot of internal symbols that we don't want
to add to the ABI if we don't have to. As long as we don't
have to make incompatible changes to functions, we can work around
that by simply using a non-versioned library for the unit tests.
Therefore we add a seperate rule here. Do this before actually
adding a version script, to avoid breakage during bisection.
