The Makefile targets 'aggregate-results' and 'clean' pretended to be
independent. This is not true, of course, since aggregate-results
needs the results _before_ they are removed.
Likewise, the tests should have been run already when the results are
to be aggregated.
However, as it is legitimate to run only a few tests, and then aggregate
just those results, so another target is introduced, that depends on all
tests, then aggregates the results, and only then removes the results.
