[Buildroot] [PATCH v6 0/9] bump/choice for qt 5.8.0

[Thomas Petazzoni <thomas.petazzoni@free-electrons.com>]

Andreas, Zoltan, Peter,

First of all, thanks a lot for all your work on Qt5. Qt is definitely a
very important package in Buildroot, so it's great to have a group of
contributors taking care of it.

I've applied those two patches. However, I am not entirely happy with
them, because the status of each module (tech preview, legacy) actually
depends on whether you consider Qt 5.6 or 5.8. So maybe we should
remove this classification entirely, and instead document the status of
each module in their Config.in help text. This way, we can say in the
help text: "This module is considered tech preview in Qt 5.6, but is in
the core Qt since 5.8", etc.

Could one of you work on this? It should be an easy thing.

This commit is applied.

This is applied, with a number of changes:

    [Thomas:
     - tweak commit log about GStreamer related changes, suggested by Arnout
     - move the gcc 4.8 dependency from the main qt5 option to just the
       qt5.8 selection, so that qt5.6 can still be built if gcc < 4.8 is
       used. Noticed by Arnout.
     - rename the options of the version selection to not include the
       version number itself so that we don't have to keep legacy
       symbols. Noticed by Arnout.
     - introduce changes to qt5quickcontrols2.mk needed to handle qt5.6
       vs. qt5.8, borrowed from a later patch in the series.
     - add patch for python-pyqt5 to fix the build with Qt 5.8.
     - add fix to libv4l.mk from Peter Seiderer to fix the build with Qt
       5.8.
     - renumber patches for 5.6.2, suggested by Arnout.]

This is not applied, as there were still some comments. Could you
address them and resubmit an updated version?

Applied.

Not applied, it's related to "qt5declarative: enable Quick for non-GL
platforms for Qt 5.8.0".

Applied, ans also the corresponding python-pyqt change.

>   python-pyqt5: Fix for Qt 5.8.0

Applied, but merged into the 5.8 bump, since it's needed. I've also
merged into the same commit the freetype related build fix from Peter
Seiderer, and the v4l2 fix also from Peter.

Could you monitor the autobuilders in the next few days and see if Qt
related issues pop up?

We really wanted to have Qt 5.8 in 2017.02, for which we will release
rc1 in a few days. It was a bit of a risky decision, so we hope that we
won't have too many build issues following this bump. And if we do,
that we'll have your help to fix them up :-)

Thanks again!

Thomas
