PATCH 1/1 libv4l: disable clang

For the time being, disable clang that is used to build BPF (in-kernel bytecode machine) protocols.
Indeed, if an old version of clang is found on the host, it could be used to build object files with a "None" architecture which will be rejected by support/scripts/check-bin-arch

Fixes:
