Comment # 2 on bug 1089601 from Michal Srb

The `xf86DisableRandR` function was used to disable RANDR 1.1 in case the
driver was about to initialize RANDR 1.2+ instead.

That patch changed the logic and it is no longer necessary to disable 1.1 with
that function. X server will let all drivers initialize RANDR on their own and
only if none did, then it will initialize the 1.1.

For the time being we can re-add empty `xf86DisableRandR` to fix the linking
issue. Everything should work just the same.
