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.
