e.g. x86_64-linux assumes 32-bit code can be executed, even if it is kconfig'd out. Similar with 64-bit Arm cores that can't execute 32-bit code.

hmmm. i think the most trivial thing to do is to write a trivial -m32 target that we try to execve to find this info. the alternative is assembly crimes that aren't good.
