Yes. You also needed to manually --enable-dri3. I've just fixed it that so we
build DRI3 (if available) and just limit to DRI2 at runtime (and so allow
selection of DRI3 with a normal build).

Allow runtime selection between DRI levels
Rather than imposing a maximum DRI level at compile time by compiling
out unwanted protocol handlers, default to limiting it at runtime so
that we can switch between any level.
