From: Zhai Edwin <edwin.z...@intel.com>
Add an PACKAGECONFIG in qemu to disable GL acceleration:
* By default configure try best to enable GL acceleration and fail when missing
host dependency(libSDL and libGL).
* End user can also choose to turn off GL capability, thus remove the host
dependence in building.
[YOCTO #2407] got fixed.
