[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=e1fc11b4fe637aa7ca029447d1963a318d159fb8
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

This patch adds a new package for the OpenGL, OpenVG and EGL
proprietary implementations specific to the Vivante GPU of i.MX6
processors.
