[yocto] Possible Cedartrail PVR build race

[Chris Tapp]

I think I have a build race condition for a project:

1) Using the meta-intel/cedartrail BSP;
2) Building under Danny 8.0;
3) Custom image;
4) Custom task;
5) OpenGLES application which runs under 'X'.

If I do a clean build (i.e. after deleting tmp/ sstate-cache/) then my application produces 'fuzz' on the screen - some vertical strips visible, but nothing recognisable.

If I then 'cleanall' the image, task and application and rebuild the image I get an image with an application that works as expected.

I suspect this is something to do with some warning messages I get during the clean build:

   /media/SSD-RAID/build-danny-cedartrail/tmp/sysroots/cedartrail/usr/lib/libEGL.so

Is there something I can add to my image/task/application .bb to prevent this?
