[Buildroot] [PATCH 5/9] libsigrok: depends on gcc >= 4.7

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

Thomas, All,

On 2015-08-04 20:00 +0200, Thomas Petazzoni spake thusly:
> Until recently, only the C++ bindings of libsigrok needed a recent
> compiler because they are written in C++11. However, now, libsigrok
> itself is written in C11, which is only available since gcc 4.7.

Here are a few autobuild failures for this:  ;-)
    http://autobuild.buildroot.org/results/1d7/1d75497009f1e3b06236b3409fd768dcf7956b87/
    http://autobuild.buildroot.org/results/563/563378e3f6320980153c8c972ceba5e913fe933f/

With those added to the commit log;

Reviewed-by: "Yann E. MORIN" <yann.morin.1998@free.fr>

Note that I have not even attempted to build it with a gcc-4.7 to
validate. This is only a review...

Regards,
Yann E. MORIN.

> So, this commit replaces the CodeSourcery-specific exclusions by a
> proper dependency on gcc >= 4.7.
> 
> The sigrok-cli and pulseview packages, which select libsigrok, are
> also updated accordingly.
