perf build: Fix single target build dependency check
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.
