'build' script: complain if we are not in a valid branch From: Nelson Castillo This is a known problem and it is starting to become a FAQ. People get an error message when they try to build a kernel and they are not in a valid branch of their local repository. When it happens git-branch will print something like: * (no branch) andy-tracking balaji-tracking With this patch we make sure we are in a valid branch when building the kernel using the build script in order to avoid OM developers some trouble. How? We print a nice message if we are not in a valid branch and then stop. Please feel free to edit the error message if you think it is not clear enough. Thanks to Werner Almesberger for his advice on shell scripting.
