After bisecting, the following commits seems to be the cause:

e8b38ca202fbe8c281aeb81a4b64256983f185e0 is the first bad commit commit e8b38ca202fbe8c281aeb81a4b64256983f185e0 Author: Plamena Manolova plamena.manolova@intel.com Date: Tue May 31 17:32:38 2016 +0100

egl: Check if API is supported when using eglBindAPI.
