The game (client, server) can be compiled successfully on PPC64LE

I hope my PR would get merged:

Does the VM work on LE?

Yes it does

Nice work. I have one question: for PPC64 BE, would Power Mac G5s running 64-bit Linux run afoul of the -mcpu=power7 flag?

I don't have the answer but I think it should work.

PPC970 and POWER7 doesn't match.

Yeah, there needs to be another condition to account for that possibility - ppc970 and friends are POWER4 derivatives and have their own special mcpu entries.
