This was easy to solve: I switched where libepoxy was looking for EGL and GL 
libraries to use libglvnd rather than mesa, as well as adding libglvnd as an 
input. Also added libglvnd as an input into xorg-server.

Looking at other packages that depend on e.g. libepoxy/mesa/etc. seems like 
many will need libglvnd as an input now? Is that what we want to move to (I 
take it is optional, but perhaps a move in the right direction)?

In either case, I'd love to see this in core-updates so we can make fixes to 
dependent packages as needed, since there are many that depend on mesa, 
libepoxy, xorg-server, and so on.
