I'm not aware of Arnd's work for this but I checked all architectures and sent patches for those which needed it (for endianness and machine size). Admittingly, I didn't even try to make the changes at top-level but, as you have noticed, architectures with a fixed endianness usually doesn't set the CONFIG option. I'll let things settle a bit and then I'll look what can be done to simplify those things.
