Cross-compiling isn't really a supported thing, because there's too
much stuff we can't find out about the target system in that case.
If it works for you, great, but if it doesn't we're unlikely to put
a lot of effort into fixing it. You might be able to manually
correct whatever mistaken assumptions configure made (by editing
its output files). It's hard to see how that could be automated
though.
