Break up the firmware build into a 'make export' phase for NuttX on a per-board basis, and then a separate per-config phase that allows us to avoid re-building NuttX all the time, and ship more than one firmware config for a given board.

This is a first cut; it builds one firmware for each of FMU and IO.
