qemu: Disable native emitter for the MICROBIT board.

Browse Source 
The Micro:Bit machine definition in Qemu has soft MMU support enabled,
which is currently not compatible with the way MicroPython generates code
that needs to call back into non-emitted code.

As a stop-gap solution, the native code emitter for the MICROBIT board is
turned off.
