So I have a GDB stub written in C / libopencm3 that can be used to
bootstrap into a staapl protocol.  What is the next step?

The stub can call C functions.  Make a small staapl ARM program that
behaves as a C function.  E.g. add1().

Now, going back to the existing code: an Staapl serial protocol
handler is running in qemu.  Host this inside the libopencm3 GDB stub.
