[meta-freescale] [meta-fsl-arm]: Wayland/Weston issue with gpu-viv-bin-mx6q 3.5.7-1.0.0-alpha.2

[Post Lauren-RAA013]

Wayland Weston is fully support in 3.10.9-1.0.0 so it is better to use that version over 3.5.7. There were some additional components that needed updates for Weston to work outside of the graphics package that are in the 3.10.9-1.0.0 alpha release.  These changes are in master-next now.

Subject: [meta-freescale] [meta-fsl-arm]: Wayland/Weston issue with gpu-viv-bin-mx6q 3.5.7-1.0.0-alpha.2

I've been integrating the gpu-viv-bin-mx6q binaries from meta-fsl-arm into Timesys Factory, but I've encountered a linker issue which I think illustrates non-functional lib{EGL,GAL}-wl in the 3.5.7-1.0.0-alpha.2 version yocto provides. 

I'm not sure if this is an issue that needs to be fixed, given the impending jump to 3.10, but I figured I'd share it just in case.

Before getting into further details, it's worth stating that the 3.10 stuff in master-next is fine (KUDOS!) This is just an issue with the master branch. In fact, replacing libEGL-wl.so and libGAL-wl.so with the binaries found in the
3.10 version in master-next fixes this issue.

Now the details:
With 3.5.7-1.0.0-alpha.2, linking weston throws several undefined symbol errors around these symbols:

gcoOS_CapturePointer
gcoOS_CopyPixmapBits
gcoOS_CreateClientBuffer
gcoOS_CreateContext
gcoOS_CreateDrawable
gcoOS_CreatePixmap
gcoOS_CreateWindow
gcoOS_DeinitLocalDisplayInfo
...(46 total, all named gcoOS_*)

Using objdump to compare the symbols in 3.5.7 to those in 3.10 version, all of these symbols are defined in the 3.10 version of libGAL-wl.so. They are either *UND* or not found in the 3.5.7 versions of these binaries.

I've run into this with Timesys tools -- my attempts to build weston in yocto meta-fsl-arm master have been all unsuccessful--clearly the fixups to weston in master-next are needed for a start.

For Timesys, I think I'll just drop in the 3.10 gpu-viv binaries, and test using that. weston is working in our environment with this configuration, but I need to revisit X, DFB, and fb.
