linux-yocto: allow configuration of arbitrary branches
When building an external tree or bootstrapping a BSP the
external branch may not have been checked out. The tools now ensure
that the tree is ready for configuration, so we no longer need to
force the checkout of the external branch.
This change is coupled with some kern tools tweaks as follows:
40d9bab updateme: allow the location of board descriptions based on defines
59859ca createme: use branch name when creating meta data
91b4275 configme: determine meta branch based on directories, not branch naming
f5a915c kgit-meta: make branch creation and renaming more robust
