API headers from libbpf should not be accessed directly from the
library's source directory. Instead, they should be exported with "make
install_headers". Let's make sure that bpf/preload/iterators/Makefile
installs the headers properly when building.

-$(BPFOBJ): $(wildcard $(LIBBPF_SRC)/*.[ch] $(LIBBPF_SRC)/Makefile) | $(OUTPUT)
+$(BPFOBJ): $(wildcard $(LIBBPF_SRC)/*.[ch] $(LIBBPF_SRC)/Makefile)            \
+          | $(LIBBPF_OUTPUT) $(LIBBPF_INCLUDE)

Would it make sense for libbpf's Makefile to create include and output
directories on its own? We wouldn't need to have these order-only
dependencies everywhere, right?

Good point, I'll have a look at it.
