You have a point.  Backing out parallel-tests is not the solution
though, at least not one I like.  ;-)

One way forward is to use separate build directories for the static,
conf, shared, undef, nopic, variants of the tests.  And their install
directories.  That way they should be as decoupled as previously again.

I'll work on a patch.
