[Buildroot] MAKEALL script

[Ulf Samuelsson]

Would like to easily be able to build multiple projects without going
through the hassle of copying something to .config all the time.

The idea is to be able to save the current .config somewhere
and be able to easily retrieve it.

The save is performed by 

$ make saveconfig

This saves a project with PROJECT=myproject into
"project/myproject/myproject.config"


Once saved, the project can be rebuilt by

$ make BOARD=myproject


Here is how a MAKEALL can be implemented (Once projects are available)!

#!/bin/bash
make BOARD=at91sam9261ek
make BOARD=generic-x86
make BOARD=atstk1000

The main difference between this and the <myproject>_defconfig
is that most projects will be generated by the user
and not statically included in the trunk, where the defconfig
stuff is more appropriate.
