Yes, *I* would say so, but the LO build thinks otherwise!

I specifically did 'make build' in order to avoid the tests, but the
build system compiles the tests anyhow.  There are LOTS of other ways
in which cross compile is broken.  It seems clear that it really isn't
supported or tested, and so I don't expect too much.  My goal is just
to get it working, somehow, for a particular setup.

Ok, I'll take a look.

Thanks,
