I actually did this once for a big project with many subdirectories, 
using automake. I ended up with a single, top level makefile with all 
the properties you describe. However, the other property it had was that 
it was so big it took make 15 seconds to parse it. Although it slightly 
improved a complete rebuild, the overhead made frequent small, partial 
rebuilds too annoying. I junked it.
