Changing the 'testSuites' field of the PackageDescription to be a
'Maybe [TestSuites]' instead of just '[TestSuites]' would do.
('Nothing' == disabled tests and 'Just []' == no tests.) A patch like
that would touch a lot of places in the test suite code, but not in a
meaningful way.  Should I write a patch to do it this way?
