4.9-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit b44b136a3773d8a9c7853f8df716bd1483613cbb ]
According to Documentation/kbuild/makefiles.txt all build targets using if_changed should use FORCE as well. Add missing FORCE to make sure vdso targets are rebuild properly when not just immediate prerequisites have changed but also when build command differs.
