hacky workaround ebuild for USE=libglvnd

The new nvidia beta driver finally adds support for render offloading (needs four patches for xorg-server to work) but this relies on fuctional glvnd.
http://download.nvidia.com/XFree86/Linux-x86_64/435.17/README/primerenderoffload.html
Attaching a hacky-whacky workaround ebuild and env file which only works with the old lib32/lib64 locations for people needing this and to point out the rising urgency for Gentoo to have a functional glvnd setup.

env file for files dir, needed by hacky ebuild

Adds an LD_LIBRARY_PATH set to the current install location of the nvidia libs to avoid reworking the nvidia-drivers ebuild and changing file locations.

Please attach patch for ebuild, not full ebuild, and with "Signed-off-by".

Patch against nvidia-drivers-435.17.ebuild

Adding a clean solution patch changing file locations to standard, skipping the media-libs/libglvnd provided libraries and eselect-opengl calls in the USE="libglvnd" case.

Tested nvidia-drivers/nvidia-drivers-435.21 with USE="libglvnd" and USE="-libglvnd", both cases work fine so closing this.

Thank you for testing. I am surprised it works as is without the original env.d addition.

[Comment 7 Maik 2019-09-02 19:07:26 UTC]

The env.d addition was just a quick-n-dirty hack to emulate eselect-opengl behaviour. This was replaced by changing the library path to standard:
+	if use libglvnd; then
+	        local GL_ROOT="/usr/$(get_libdir)"
+	else
+		local GL_ROOT="/usr/$(get_libdir)/opengl/nvidia/lib"
+	fi

[Comment 8 Ostashevskyi Viktor 2019-09-09 17:04:51 UTC]

It would be nice to add libglvnd USE flag to xorg-server as it pulls app-eselect/eselect-opengl unconditionally.

[Comment 9 Maik 2019-09-09 17:12:20 UTC]

For xorg-server, see bug #692168
