When the U-Boot base directory happens to have the same name as the branch that buildman is directed to use via the '-b' option and no output directory is specified with '-o', buildman happily starts removing the whole U-Boot sources eventually only stopped with the error message: OSError: [Errno 20] Not a directory: '../<branch-name>/boards.cfg Add a check to avoid this and also deal with the case where '-o' points to the source directory, or any subdirectory of it. Finally, tidy up the confusing logic for removing the old tree when using -b. This is only done when building a branch.
