The reason is that the top-level 'Makefile' processes util/map.o as an implicit rule and if util/map.o exists make considers the 'util/map.o' target as done and will not nest into Makefile.perf. Adding FORCE for '%', because that's what we want to nest into Makefile.perf for any target. Adding Makefile into phony targets, because make tries to rebuild it and it's also resolved as '%' target.
