In the build failure
http://autobuild.buildroot.org/results/c18fb7f1ac81496db9c3a4e91ea028a26ca600b0/build-end.log
that you point, the architecture is reported as "None", not as "Linux
BPF". Am I misunderstanding something here ?

As a first step, could we explicitly disable building BPF protocols,
before we merge the necessary LLVM/V4L logic to build these properly ?

Thanks,

Thomas
