qemu: warn user if nVidia libGL is detected (leads to qemu segfault) 

nVidia's OpenGL libraries are known to have compatibility issues with qemu,
resulting in a segfault. As different workarounds are required for the different
distributions, just warn the user to explain the qemu segfault to follow, and
suggest a workaround using LD_PRELOAD.

[YOCTO #649]
[YOCTO #698]

(Original patch from Edwin, Darren modified warning and git commit wording)
