I don't know the exact details for using a BDM cable, but see
the dejagnu manual; testing can be done on a variety of boards
and through a variety of connections, protocols and

Yes, this is IMHO the easiest way to do it (once code is in
place that is; after setting it up the first time).

No you don't; you just need I/O-hooks in the simulator.
Besides, most of the gcc testsuite isn't even hello-world;
it's abort () or exit (0).

See (here we go again) the
<URL:> instructions.

There's a newlib and a libgloss port for m68k, and it seems the
necessary simulator low-level bits have been written, but I
don't know for what simulator, and I see no m68k simulator in
sim/ or sid/.
