[Mesa-dev] [PATCH 1/3] dri: Require libudev-dev for building DRI on Linux.

[Eric Anholt]

The loader infrastructure for everything but DRI2 requires that udev be
present, so we can figure out an appropriate driver from the fd.  We don't
have a portable solution yet, but presumably it will similar lookup based
on the device node.

It will also be even more required for krh's udev-based hwdb support,
which lets us have a loader that actually loads DRI drivers not included
in the loader's source distribution.
