I think this information is somewhat already provided by the dpkg
arch tables. Any architecture with a 64-bit CPU and with a 32-bit
ABI, as defined by the cputable and abitable files.

So this would include x32, arm64ilp32 and the mipsn32* arches.

AFAIR the OpenBSD port on 32-bit CPUs would be affected too as they
did a scorched-earth migration to 64-bit types ignoring any backwards
binary compatibility. But then I guess we can just ignore that one. :)

Thanks,
