The problem is that .ko's on amd64 are handled by link_elf_obj.c and not
link_elf.c, thus if link_elf.c is first in the list of linker file handlers,
then every .ko on amd64 is first going to try link_elf.c which fails and
emits the error and then get loaded successfully by link_elf_obj.c. Probably
what should happen is that the linker error message should be cached somehow
and only print out the last error if the overall load fails.
