Ah - I see what needs to be done. I need to point configure to our cross compile tools and not the native system. Not a straightforward thing to do in open embedded's bitbake-based build environment. It automates the whole thing from grabbing the tarball from the ftp site to compiling and then staging the resulting output to the correct target rootfs tree. I'll have to override the defaults being passed to configure.
