A lot of fixes for these build problems have now landed in mainline, and
we could backport them as soon as they are considered stable enough.
If all of these make it into stable, we should have a clean build on MIPS and
ARM, and only the KASAN warnings remaining x86 and arm64.

I'm still working on the fix, the same thing happens in mainline.
