4.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Philipp Rudo <pr...@linux.ibm.com>
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.
