I didn't mean to imply that you need to check, just that it's likely to
not work (regardless of endianness) and you should be aware of that.
powerpc and sparc aren't "tier-1" architectures anyway, so ordinary
users are unlikely to run into them, and there are probably lots of
ports that won't run on them. The tinderbox doesn't even build for
