perf tools: Fix bison OUTPUT directories dependency
The bison and flex C objects don't have dependency for creating output
directories.
This could lead to build failure if the one of those objects is picked
up by make to be build as the first one (reported by Arnaldo).
Also following make fails:
$ rm -rf /tmp/krava; mkdir /tmp/krava; make O=/tmp/krava util/pmu-bison.o
BUILD: Doing 'make -j4' parallel build
[ SNIP ]
BISON /tmp/krava/util/pmu-bison.c
FLAGS: * new build flags or prefix
bison: /tmp/krava/util/pmu-bison.output: cannot open: No such file or directory
make[1]: *** [/tmp/krava/util/pmu-bison.c] Error 1
make[1]: *** Waiting for unfinished jobs....
make: *** [util/pmu-bison.o] Error 2
Adding bison objects dependency for output directories (flex objects
depends on bisons').
This fixies the make_util_pmu_bison_o_O make test.
