On the Pi 1 now the binary has three time the size (with a lot of 0x00
in it) and at least RTEMS starts. But it runs into an exception quite
fast. I'll investigate that a bit.

@Niteesh: For the Pi 3 I would expect that it still doesn't print
anything on the console due to the different UART pins.

The output on the Pi 1 is:
