 Well, I had cases where I did that, and offhand I can find two reasons:

1. You want to verify `gdbserver' itself rather than GDB, in which case 
   you may even run it locally (i.e. where the remote target is really 
   `localhost').

2. You want to test a feature (e.g. an extra register set) only your 
   target system has and it is too slow or unequipped to run DejaGNU 
   itself.
