             configure: Link to either OpenGL or OpenGL ES - not both

 - linking to both libraries causes unexpected behaviour on some legacy
 drivers - notably nvidia (and maybe some Intel mesa) - leading to either
 a hard crash at startup or falling back to llvm pipe (software
 rendering)
 - it also appears to impact behaviour of EGL DMABUF support on the Pi4 -
 which needs an additional fix following this change
 - we default to OpenGL and check whether Qt was compiled for GLES2 - and
 if so only search for GLES2.
 - in case Qt support is misdetected an additional configure option is
 added to force OpenGL ES
 - note however that this is ONLY intended as a workaround for
 misdetection - Qt will still load the version of OpenGL it was compiled
 for. Linking to GLES is not required to actually use GLES on desktop
 platforms (this can be enabled with 'MYTHTV_NO_EGL=1
 MYTHTV_OPENGL_ES=1')
