[Buildroot] [PATCH] jack2: allow to choose the mode to operate jackd

[Yann E. MORIN <yann.morin.1998@free.fr>]

Antoine, All,

On 2015-05-12 10:03 +0200, Antoine Tenart spake thusly:
> jack2 allows to use three modes:
> - A legacy jackd service alone.
> - A DBUS jackd service alone.
> - A mixture between the standalone jackd and the DBUS jackd.
> 
> This patch adds the possibility to choose between these three modes,
> while the legacy jackd was the only option before.
> 
> In addition, the jack_control tool is removed when the DBUS jackd is not
> available, as this tool is used to control it.

I've tried to update that patch, clean it up a bit, and I just sent a
new version:
    http://lists.busybox.net/pipermail/buildroot/2015-December/148388.html

I'd like your opinion on this new version.

Regards,
Yann E. MORIN.
