PC Hosted variant

THIS IS INCOMPLETE - ONLY SUPPORTS SWD AT THE MOMENT

This variant will use any BMP probe with recent firmware as a remote actuator, with the actual probe code running on the PC. The BMP itself is 'dumb' and doesn't do anything (although any secondary serial port remains available).

To use it, compile for the pc-hosted target and then connect to your normal BMP GDB port;

src/blackmagic -s /dev/ttyACM0

...you can then connect your gdb session to localhost:2000 for all your debugging goodness;

$arm-eabi-none-gdb (gdb) monitor swdp_scan Target voltage: not supported Available Targets: No. Att Driver 1 STM32F1 medium density M3/M4 (gdb) attach 1 Attaching to program: Builds/blackmagic/src/blackmagic, Remote target 0x08001978 in ??

...note that the speed of the probe in this way is about 10 times less than running native. This build is intended for debug and development only.
