I can get a successful build with my kernel branch where I've merged
the latest 4.1.y upstream stable release into the Raspberry Pi 4.1.y
branch (https://gitlab.com/oryx/linux-oryx-rpi). I don't have the time
to bisect this right now but one commit stands out as an obvious
candidate for being the fix:

compiler-gcc: integrate the various compiler-gcc[345].h files
https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?h=linux-4.1.y&id=f320793e52aee78f0fbb8bcaf10e6614d2e67bfc

I can also get a successful build using the recipe for the 4.4.y branch
in meta-raspberrypi. The Raspberry Pi repository has moved over to the
4.4.y branch as the default, we should probably do the same in
meta-raspberrypi.

Thanks,
