#     kbuild: change need-modorder implementation slightly
#     
#     Align with the need-builtin implementation.
#     
#     I also added need-modorder=1 to scripts/link-vmlinux.sh to make it more
#     future-proof; currently, we have no module in the init/ directory, but
#     if we had a one, scripts/Makefile.build would show a false positive
#     warning.
