If anyone has any objections, please let me know. ------------------ From: Philipp Rudo commit c315e69308c739a43c4ebc539bedbc1ac8d79854 upstream. Without FORCE make does not detect changes only made to the command line options. So object files might not be re-built even when they should be. Fix this by adding FORCE where it is missing.
