FWIW, OpenEmbedded/Yocto Project knows how to cross compile a large chunk of open source software and build functional images from source. It runs autoreconf on most of the software so if you wanted to test this against a large pool of software, it would allow that. I'd be curious on the speed comparison if you do as autoreconf spends most of it's time in m4. Cheers, Richard
