 processor like 970 or 7450?  I actually have little idea just what format
 those GO files are.

 The binary GO output files seem to follow this architecture: `guild
 compile --target="powerpc-apple-darwin9"`. Clearly 32 bit, but – in the
 prebuilt directory is no 64-bit-big-endian sub-directory to support modern
 64 bit PowerPC hardware, which simply is not necessary because the PPC 970
 can execute the 32 bit big-endian code for PPC 7400 or PPC 7450.
