Yes, I broke it, sorry!

There's a fix queued in arm64/fixes/core already (04c4927359b1). Using a 
different toolchain is another option, since the one I'm currently using 
(gcc-linaro-7.2.1-2017.11) builds it just fine, which is how I managed 
to create this mess in the first place ;)

Thanks,
Robin.
