That sounds like "uname -a" or "uname -m" is what you want. You want to
select the right binary, or verify it is the best choice even when it does
run in a lesser way.

So what binary would you choose for a 64-bit kernel with a 32-bit runtime?
I think a 64-bit program will have some issues in that. You're probably
already testing the runtime environment. But if they are mixed like that,
what is your choice?
