[oe] meta-angstrom commit 75f0f25e breaks build of opencv from meta-openembedded

[Steffen Sledz]

Commit 75f0f25e55f0745a011640b5c81d88be99366f45 in meta-angstrom/recipes-tweaks (branch angstrom-v2014.12-yocto1.7) introduces version 10.5 of libav.

This version does no longer provide defines like CODEC_ID_H264 which are needed for opencv 2.4.9 from meta-openembedded/meta-oe/recipes-support (branch dizzy).

I'm not sure if this problem occurs in the master branches too, but the dizzy/angstrom-v2014.12-yocto1.7 branches are unusable for some of our applications beacause of this problem at the moment. :(
