[Buildroot] Runtime generation of board support version 2

[Ulf Samuelsson]

Add runtime generation of board support version 2

$ make saveconfig
will save the current configuration to project/$(PROJECT)

$ make getconfig
will copy the saved config to .config

$ make BOARD=<myproject>
will use project/<myproject>/<myproject>.config
instead of .config

(There is a doc update as well, not included here)

Moved the saveconfig to project/project.mk and added getconfig
Now, the .config file will be updated so that the stuff in 
project/$(PROJECT) will be used for Linux, UCLIBC and busybox.

Comments?
