From 514ec438927cc2913f365ce766091cfe03fea6b7 Mon Sep 17 00:00:00 2001

Subject: [PATCH] kbuild: add missing FORCE where $(call if_changed, ) is used

FORCE is needed for $(call if_changed,...) to be evaluated every time.
Otherwise, the command is not executed when the command line has
changed but any prerequisite has not been updated.
