I want to be able to run it against gcj, gij, kissme, kaffe, sablevm,
jamvm, jdk, etc.  Not really all at once, just depending on what I'm
using at the time.  I don't think the clean, reconfigure, make dance is
appropriate for this task.

Nothing wrong with that, but it wouldn't hurt to provide something out
of the box would it?

It's pretty nasty.  I have a feeling it turns some people away when it
isn't very clear how to set it up, run it, add or modify a test, and
re-run it.

The intention is for standalone use.  Although one could probably keep
the Makefile.am/configure as-is, it would clean things up considerably
to move such their current functionality into a re-usable script.

Right, I have a feeling that to do what I want I'd have to modify some
part of this though probably not a great deal as long as tests can still
be executed without installing.
