Thanks James. I'm going to mark this one as Changes Requested, as we
are soon going to merge the series from Yann that reworks how we handle
the interaction between enabled packages and kernel config options, see:

  http://patchwork.ozlabs.org/project/buildroot/list/?series=168565

If you can resend on top of this series, it would be ideal. Thanks!

Best regards,

Thomas
