That's exactly the problem which is solved by using distcc or scratchbox. distcc basically sends preprocessed source to another machine and expects an object back. So you run the build on a machine of the target arch (or an emulator), but the compiler part is actually a small program which sends the source to the fast machine running the cross compiler and expects the object code back. Scratchbox provides a sandbox on the machine doing the cross compile, in which target binaries can be executed by either running them on a target board sharing the sandbox filesystem using NFS or by running them in qemu. Cheers, Peter (p2).
