I talked to Eduard off-list, and in his view this is the most
appropriate way to leave a catch-all dependency:

    $(OUTPUT)/$(TRUNNER_BINARY): $(TRUNNER_BPF_OBJS)

As opposed to original:

    $(TRUNNER_TEST_OBJS): $(TRUNNER_OUTPUT)/%.test.o:			\
                      ...
   		          $(TRUNNER_BPF_OBJS)				\
                      ...

Or v3:

    $(TRUNNER_TEST_OBJS:.o=.d): $(TRUNNER_OUTPUT)/%.test.d:		\
                            ...
                                $(TRUNNER_BPF_OBJS)			\
                            ...
