Right.  I think that that the stuff I just added shows how to compile 
something -- but running stuff is a little harder.  You should be able 
to use the DejaGNU remote stuff, though; something like:

   set output [remote_exec target "test_locales"]

will do what you want.  Then, you want to look at the output from the 
program; you can't trust the exit code, in general.
