perf tests: Fix *.o make tests

Enable and fix *.o object make tests. Following tests are now available:

  $ make -f tests/make make_perf_o_O
  - make_perf_o_O: cd . && make -f Makefile O=/tmp/tmp.iF5vI5emGy DESTDIR=/tmp/tmp.epDPFVhH0s perf.o
  $ make -f tests/make make_util_map_o_O
  - make_util_map_o_O: cd . && make -f Makefile O=/tmp/tmp.BWuMf55ygC DESTDIR=/tmp/tmp.QbGBRF95oP util/map.o
