This is WAY overkill if all you want is the exit status.  This
is why avrtest has magic ports for exit and abort.  You write
the exit code to the exit magic port and poof exit(value) is
called.  This is the way all the simulators in gdb work.

I have added these to my tree but haven't cleaned them
up and added documentation yet.

I don't dispute the value of an object dump but it is overkill
for getting exit status values from tool tests.
