[PATCH] dri1: Don't bother asking the loader about drmGetLibVersion

[Adam Jackson]

This was added for DRM_IOCTL_SET_VERSION support, which has been around
for over ten years now. Since we require ≥2.3.0 in configure.ac this
would really only protect you if you managed to build against a modern
libdrm but run against one that's more than 7½ years old, which, doctor
it hurts when I do this.
