Details:

on openSUSE 13.2, Qt version 4.8.6, in the gui, when trying

plot(1:10)
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast

The same errors happen once during make check, in 
libinterp/corefcn/graphics.cc-tst

According to this question on stackoverflow
<http://stackoverflow.com/q/27659516/3565696>, and this bug report
<https://bugreports.qt.io/browse/QTCREATORBUG-8727>, the problem is that
LD_LIBRARY_PATH is overridden somewhere.

Like in this reports, I'm using the proprietray nvidia drivers.
They add /etc/ld.so.conf.d/nvidia-gfxG03.conf which contains
/usr/X11R6/lib64
/usr/X11R6/lib
and indeed 
/usr/X11R6/lib64/libGL.so -> libGL.so.1
/usr/X11R6/lib64/libGL.so.1 -> libGL.so.340.76
/usr/X11R6/lib64/libGL.so.340.76
should be used.

But there are also
/usr/lib64/libGL.so -> libGL.so.1.2.0
/usr/lib64/libGL.so.1 -> libGL.so.1.2.0
/usr/lib64/libGL.so.1.2 -> libGL.so.1.2.0
/usr/lib64/libGL.so.1.2.0
