I have the same problem with binutils-2.27 on gentoo. Worked around it
by adding " -b coff-x86-64 " to the ld command line before $(note_file).

Running with  gentoo-sources-4.8.12-gentoo-r1 as dom0 kernel. Compiled
with gcc set to x86_64-pc-linux-gnu-5.4.0 .


Apart from that seems to be running nicely, in early test :-)
