perf tools: Fix parallel build
Parallel builds of perf were failing for me on a 32p box, with:
* new build flags or prefix
util/pmu.l:7:23: error: pmu-bison.h: No such file or directory
...
make: *** [util/pmu-flex.o] Error 1
make: *** Waiting for unfinished jobs....
This can pretty quickly be seen by adding a sleep in front of the bison
calls in tools/perf/Makefile and running make -j4 on a smaller box i.e.:
sleep 10; $(QUIET_BISON)$(BISON) -v util/pmu.y -d -o $(OUTPUT)util/pmu-bison.c
Adding the following dependencies fixes it for me.
