util/abuild: Print list of failed boards at the end of the abuild

When running abuild outside of jenkins, because all of the builds are
    printed intermixed, it's easy to miss when a board has failed the build
    by looking at the output.  This saves a list of failed builds and prints
    the list at the end of the run.

- Add a command line option to mark when abuild is being called
    recursively.
    - Add all failed builds to a list.
    - Print the list when a non-recursive abuild run exits.
