Frontend Crash with nvidia 334.21 libraries

Description

Various reports of mythfrontend crashing with the nvidia 334.21 libraries.

​https://bugs.gentoo.org/show_bug.cgi?id=501670

​https://bbs.archlinux.org/viewtopic.php?id=178366

​https://devtalk.nvidia.com/default/topic/691399/-334-16-crash-in-libglesv2-with-glgenbuffers-/

I currently suspect that the issue occurs because 334.21 drivers now include the libGLESv2 library and mythtv tries to dynamically load this, even if it was compiled with opengles disabled. See

​https://github.com/MythTV/mythtv/blob/master/mythtv/libs/libmythui/mythrender_opengl.cpp#L805

Patch coming shortly.

This bug appears to be happening again with Nvidia's v355.11 drivers.

Also this time, for whatever reason, linking to their libGL forces a linking to libGLES. This wasn't the case with the earlier version of nvidia's GLES implementation. While I'm currently trying to build QT + mythtv with EGL support to see if the problem goes away, I was perfectly happy using GLX.

Please open a new ticket, as this is potentially a different issue and relates to a different version of the nvidia drivers.

Thanks
