Are the distutils unittests disabled?  And if so is there a reason?  I was looking to add test cases to my PR and found that I couldn't get them (or indeed any distutils unittests) to run when trying to only target the distutils unittests.

From looking at the code my guess is that the Python test suite was ported to use the load_test protocol sometime after Python-3.2 but distutils was missed.  I can submit a PR to change that unless there's a reason it is the way it is.
