tile: fix dependency and .*.cmd inclusion for incremental build
Build targets using if_changed(_rule) must depend on FORCE so that they are evaluated every time. In order to include .*.cmd files correctly, build targets added to "targets" must not be prefixed with $(obj)/ because it is done by scripts/Makefile.lib .
