thinking about it more, the gdb port atm doesnt support FDPIC.  so if the only 
contentious point of the gdbserver code is the FDPIC handling, then i can 
simply drop that and revisit when the Blackfin/FDPIC core code is merged.

we do Blackfin bare metal every day.  from the Blackfin side of things, it's 
the same as doing Linux/FLAT.
