As Dylan pointed out I don't think you needs any extra patches for
piglit for this scenario.
Just set the variables prior to running piglit and have fun :-)
For example:
export LD_LIBRARY_PATH="/opt/rhel6/usr/lib/"
export LIBGL_DRIVERS_PATH="/opt/rhel6/usr/lib/xorg/modules/dri"
That said, you might end up in a "mess" as you'll be using(?) a mix of
rhel6 and rhel7 libraries as required by mesa - xcb*, expat, gcc_s,
llvm to name a few. LD_DEBUG=libs is your friend, but if it was me I
would port the mako package and be done with it :-)
