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.
