This should be fixed now

d3d.pc not being installed is bad, but I think it's your configuration.
I'm not sure about dri.pc, that's a good question. It's created in
src/mesa/drivers/dri, but I could see it being correct to install if the gallium
drivers are built using dri.

Ohh, yes, those are missing, I'll send patches for those

I dropped the gallium-media option, so that we could configure these as
tri-states (auto, true, false), which we need to support macOS and Windows.

Instead:
-Dgallium-omx=true
-Dgallium-va=true
-Dgallium-vdpau=true
-Dgallium-xvmc=true
(These will be turned on automatically if you're on Linux/BSD and you have
enabled a driver that supports them)

This defaults to false, so you need:
-Dgallium-nine=true

There is a patch pending for meson to warn (and eventually error) when passing
unknown command line options.
