Adding pmu-bison.o make test:

  $ make -f tests/make make_util_pmu_bison_o
  - make_util_pmu_bison_o: cd . && make -f Makefile DESTDIR=/tmp/tmp.0u99hQn8Ga util/pmu-bison.o
  $ make -f tests/make make_util_pmu_bison_o_O
  - make_util_pmu_bison_o_O: cd . && make -f Makefile O=/tmp/tmp.sWKDLGS71O DESTDIR=/tmp/tmp.htQNJAfJ0d util/pmu-bison.o
  make: *** [make_util_pmu_bison_o_O] Error 1

The 'O=' version of the test is failing at the moment, due to the OUTPUT
directory issue fixed in next patch.
