[boot-floppies] overhauling makefiles?

Many people who work on boot-floppies have commented on the (unneeded)
complexity of the makefiles. I'd be willing to spend some time trying to
clean up the build system a bit. Is this a good time to do this? I'm
sure it'll take some time to iron out all the corner cases for a change
like this, but hopefully this will make things a lot more maintainable.

As an example of what I hope to achieve, see the attached sample
top-level makefile that I hope we'll end up with (work-in-progress, does
not work yet..)

comments? volunteers to help?

# This is the top-level makefile. Try to keep this clean; we split things
# into smaller chunks so that it is managable. Generic rules should be used
# if possible, but try to make things basic so that people understand what
# is going on and don't jump through too many hoops to get what they want.
