These two are unrelated, except that FORCE is redundant for a .PHONY
target. FORCE is our idiom to tell make to always remake the target and
let us handle the dependencies manually. Listing a target as .PHONY
tells make that the target will not produce a file of the same name
(typically, "all", "install", etc).
