--- Comment #1 from Michael Catanzaro <mcatanzaro at gnome.org> ---
This turned into quite an adventure.

Eventually I tracked down the source code for the file command. I'm attaching here the magic file it uses to determine CPU architecture. It's not easy to read, but it matches our implementation of determineArchitectureFromELFBinary. Looks like the magic number for 64-bit PowerPC is 21 (regardless of endianness), and the magic number for all variants of S/390 is 22. So we could blindly add them to determineArchitectureFromELFBinary and see whether or not it works....
