So somehow they're only building the vulkan driver but not libGL or
anything else?  Still, I guess a bunch of people will need both a 32bit
and a 64bit version of the driver.  How is the 64-bit
~/.local/share/vulkan/icd.d/intel_icd.json not going to clash with the
32-bit ~/.local/share/vulkan/icd.d/intel_icd.json?  I'm just not seeing
how this solves the problem...
