linux-yocto: streamline new BSP creation
By setting BOOTSTRAP to the branch that should be used for a currently undefined BSP a build can be completed and an environment for streamlining the BSP created. With the appropriate machine.conf, and a defconfig any MACHINE can be built against and inherit the configuration of the standard yocto kernel.
