The upstream bug that stops mesa 18.2.1 being built for stretch has been resolved.
Upstream commit: dd333c66bdcb11c0d7c5 "vulkan: Disable randr lease for libxcb < 1.13" As such, the backport of libxcb 1.13 is not really required at this point. Note that certain vulkan functions won't work exactly as intended (as the back end functions in libxcb won't exist) but that is a minor inconvenience.
