Instead, you should just turn off OpenGL/OpenGLES support. Just build with -DENABLE_OPENGL=OFF. It is optional, you just lose hardware acceleration. You should hopefully have no trouble with this.

Indeed... we did such port for a customer based on WebKit-EFL (now
out-of-tree) and it worked, but was a major pain to get there due
CoordinatedGraphics and TextureMapper being heavy on GL calls...
however in our case it was software rendering only, no GL at all.
