Comment (by alpmestan):

 Well, it's not much different from `make TEST="t123 t456 t789"`, is it? We
 can support both quite easily, really. The important thing is that you
 have a quick way to take the testsuite output that lists the failing tests
 and ask hadrian to run just those, or a only subset. We might have to do
 something about the `TEST` environment variable to make sure that it makes
 it through the `build.*` scripts, to the hadrian executable.
