* Fall back to buildroot make in top-level make To make running Buildroot commands easier, define .DEFAULT rule and fall back to targets from Buildroot with necessary variables set. This makes "savedefconfig" redundant as it's been simply passed to BR. * Also implicitly fall back to 'clean' target * Fix typo
