Yet another embedded Linux build system

This one is e2factory from emlix. It joins the ranks of other embedded Linux build systems like buildroot, ptxdist, OpenEmbedded, Embedded Gentoo, and a whole host of similar projects.

We're approaching symmetry, I think - where we have a 1:1 correspondence between embedded Linux build systems and open source mp3 players.  I'm really not sure if that's a good thing or not.
