Not all AArch64 systems can run AArch32 code (needs special kernel
configuration), so I wouldn't assume anything on either arches.
I guess the least problematic would be to get config-ix to try_compile
and try_run on each arch you think should run, so that you can get x86
on x86_64 and AArch32 on 32-bit-supporting-AArch64. You should only
fail if the arch can't compile a chosen arch, but only enable the
tests if the arch can run. Warnings during CMake time would be
appropriate, I think.
