[Oberon] Oberon bare metal on the Raspberry Pi

[Charles Perkins]

I think it would be nice to have Oberon running on the bare metal of the Raspberry Pi. 

So I have been working on it and I have reached a milestone. I have retargeted the Oberon07 compiler sufficiently to create an ARM binary that, when placed on the rpi SD card, gets loaded by the rpi firmware and blinks the LED.

Here is the source code to the successfully compiled module:

The compiled code is spectacularly inefficient. But it works!

Cheers,
