Thanks for that, sending something upstream was on my todo list but I
needed to fix the breaking builds more urgently.

I'm assuming you mean libdrm's .la file references cario?

Since I pass in --disable-cairo, it never runs the pkgconfig test for
cairo and never puts the include/library options into play. I did test
that and just retested and it doesn't reference it.
