They seem to be necessary with clang 12. The recent cherry-picks have
introduced native versions of the libc++ and libc++abi recipes, and I have
managed to finish a full build of chromium-ozone-wayland-114.0.5735.198
without these changes.

In order to use latest clang, latest bcc sources are needed, this also
means that we need to use vendored libbpf as thats the newest one needed
and avoids dependencies on kernel bpf headers which maybe old and out of
sync
examples use error.h header which is not available on musl therefore
disable examples when building on musl

Master meta-browser has moved away from gcc completely even for native
portions, but those changes require master branch of meta-clang as well
for older layers where older than clang 13 is used, lets undo those
changes

Link bcc dynamically against libbpf. This reduces the size of libbcc.so
from 68 MB to 3 MB.
Backport some patches from upstream which are needed for the actual
dynamic linking.
