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) Signed-off-by: Darren Hart <dvhart@linux.intel.com> CC: Mark Hatle <mark.hatle@windriver.com> CC: Zhai Edwin <edwin.zhai@intel.com>
