[Oberon] Oberon System 3 now also runs on the Raspberry Pi Zero 2

[Charles Perkins]

Hello Rochus,

This is an achievement!

In the interest of understanding it better, I cloned your op2 and
OberonSystem3Native repositories and was able to build op2 on Ubuntu (arm)
and was able to compile all the modules and create an image.bin file.

I got stuck however in the add_files.sh script because I don't know where
to find the aosfstool. Do you have any advice?

Thanks,

Chuck
