Yay, thanks for trying.

Ah sorry.

It's the powerpc-linux-gnu-gcc one.
That is a 32 and 64-bit compiler, it's 32-bit by default, but the kernel Makefiles will pass -m64 appropriately.
You can actually build a single compiler that builds 32/64-bit BE, and 64-bit LE, but the distros don't do that for whatever reason.
cheers
