I'm working to set up a build bot for the upcoming M68k target which is 32 bits. And while
I'm at it, I can also set up build bots for 32-bit MIPS, 32-bit PowerPC and 32-bit ARM.

We need these targets in Debian and openSUSE, so I'm happy to help with this effort.

We also need the SPARC target and we have enough SPARC hardware idling and waiting for
work, so that would be a perfect application as well.

I need to become familiar with the build bot setup first as I have not done this before,
so if someone experienced with those bots is willing to assist me, that would be great.

Adrian
