Documentation: add script and build target to check for broken file references
Add a simple script and build target to do a treewide grep for references to files under Documentation, and report the non-existing file in stderr. It tries to take into account punctuation not part of the filename, and wildcards, but there are bound to be false positives too. Mostly seems accurate though. We've moved files around enough to make having this worthwhile. Signed-off-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
