To clarify, those cross-compilers are meant to be usable on any
x86/arm64/ppc64le distro from the past 5 years, and should allow
you to build kernels (but no user space) for all supported target
architectures using all supported gcc versions.

I'm not asking you to waste time reproducing the problem (it's already
solved now), just saying you probably could ;-)
