Message:

llvm: Remove BPF from targets

To use clang with BPF for v4l-utils, libbpf must be installed but it's
not a BLFS package. And I doubt if any BLFS user really uses an IR
remote control on the BLFS system. So let's not make all BLFS users
build something useless.

Note that if both clang and libbpf both exist, v4l-utils will attempt to
use "clang -target bpf" anyway even if -Dbpf=disabled is explicitly
specified (we've got enough surprise from v4l-utils building system
these days!!), so add a note to v4l-utils for people installing non-BLFS
libbpf.
