I'd imagine a related problem are the run tests in configure. They will
produce results for the platform that you run configure on. More properly,
you should run configure in cross-compilation mode (twice, and then merge the
output, as previously described), but I am not sure how that will turn out
when configure attempts to determine alignment and endianness with
compilation-only tests. You should probably check some of those results very
carefully and help it out with some cache variables.
