From: Jiri Olsa <jolsa@kernel.org>
Currently if we build a single target like:
$ touch util/map.c && make util/map.o
It will not rebuild util/map.o if it already exists and util/map.c is modified.
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.
