[Mesa-dev] [PATCH] configure.ac: Refuse to build Vulkan without DRI3

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Trying to build the Vulkan WSI code results in a failure without DRI3.
Make configure check that DRI3 is available before trying to build
the Vulkan drivers.
