Nathan reported issue with cleaning empty build directory: $ make -s O=build distclean ../../scripts/Makefile.include:4: *** \ O=/ho...build/tools/bpf/resolve_btfids does not exist. Stop. The problem that tools scripts require existing output directory, otherwise it fails. Adding check around the resolve_btfids clean target to ensure the output directory is in place.
