amd64 uses link_elf_obj.c, all the other archs use link_elf.c, hence the
duplication. link_elf.c is used to load kld's that are ELF shared objects
(i.e. foo.so) where as link_elf_obj.c is used to load kld's that are ELF
objects (i.e. foo.o). I think you are going to get this everytime you do a
kldload on amd64 because it will always try link_elf.c first due to compile
order (MI files are ordered in the makefile before MD ones), emit the
warning, and then try link_elf_obj.c.
