It looks to me like the "-D" flag for the install command isn't
available on macOS. I think the equivalent is "-d", which appears to
do something different again on GNU/Linux.

Line 752 of Makefile.in:

### Install native compiled Lisp files.
install-eln:
ifeq ($(HAVE_NATIVE_COMP),yes)
	find native-lisp -type f -exec ${INSTALL_DATA} -D "{}" "$(ELN_DESTDIR){}" \;
endif
