[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=6f5fdb6b2ebab928816e5fcd69f288d4fce5b75b
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

If acl or attr is going to be installed, add support for them to tar.

[Thomas: explicitly disable acl and attr support when the
corresponding packages are not available.]
