I completely agree with Matt.

If the system doesn't already have nouveau installed, then it there is very
low likelihood that it makes any sense to install nouveau onto that system.
It very likely does not have NVidia hardware at all. So why require it?
Let's just autodetect it and behave sanely.

Requiring libdrm_nouveau is a nuisance for developers working on platforms
where libdrm doesn't get built with NVidia support.
