Yes, the configure machinery wasn't design with cross compilation
in mind. We could probably eliminate some, even may, of the runtime
tests and replace with them compilation (plus linking) only tests.
Besides making cross compilation easier, doing so would also speed
up the configuration process.

This makes sense to me.

I don't see the patch. If you attached it, I suspect it got stripped
by ezmlm. That tends to happen when using Outlook. Other email clients
don't have the problem. If you continue to be unable to attach patches
to your posts a (less preferable, IMO) alternative is to attach them
to the Jira issue.
