Although, I've wanted to change that for a number of years. There are advantages to building lib/device. It makes it easier to customize the library. But, of course, that requires quite a bit of effort, mainly in the autotools area, and that's what has stopped me from doing it. That and we keep having perennial discussion on increase of the build-time if we went to lib/device. I argue that it is still worth it, computers get faster every year, and with avr-libc we can do a lot of building in parallel (make -j). But that's an orthogonal discussion to this thread...
