commit 8df464ebf0db8b04d0baae6a14504f3796e355a0
Author: Jeremy Bobbio <lunar@debian.org>
Date:   Sat Jan 30 13:47:47 2016 +0000

    Also use libarchive to read metadata from ar archives

    The output is more precise and less dependent on binutils version.

    The command line `ar` tool is not used any more so remove it from the
    required tools.
