Do you want to remove these also? I can't think of a reason to keep these
around:

$ git grep -Hrnwe extmod_prefix -e MODORDER -e MODULES_NSDEP
Makefile:1912: $(Q){ $(foreach m, $(single-ko), echo $(extmod_prefix)$(m:%.ko=%.o);) } > modules.order
scripts/Makefile.modfinal:33:$(extmod_prefix).module-common.o: $(srctree)/scripts/module-common.c FORCE
scripts/Makefile.modfinal:60:%.ko: %.o %.mod.o $(extmod_prefix).module-common.o $(objtree)/scripts/module.lds $(and $(CONFIG_DEBUG_INFO_BTF_MODULES),$(KBUILD_BUILTIN),$(objtree)/vmlinux) FORCE
scripts/Makefile.modfinal:66:targets += $(modules:%.o=%.ko) $(modules:%.o=%.mod.o) $(extmod_prefix).module-common.o
scripts/Makefile.modinst:60:modules := $(patsubst $(extmod_prefix)%.o, $(dst)/%.ko$(suffix-y), $(modules))
scripts/Makefile.modinst:120:$(dst)/%.ko: $(extmod_prefix)%.ko FORCE

W/ or w/o:
