Or perhaps put something in tools/tools . The master makefule is way too complex for humans, and i suspect very fragile too. I also have my own makefile that I use for custom cross builds and wouldn't mind seeing some better example than what I could come up with. As an example from time to time I read good advice from people to cross build kernel modules or individual binaries which I always forget. They would fit well in this extra make file.
