I deleted /usr/obj/usr because this laptop only has
about 5 GB of free diskspace, and rebuilding all
installed ports with a populated /usr/obj/usr eats
up that 5 GB very quickly.  Before clang/llvm, a 
new world/kernel build took about 2 hours.

I've now discovered that it is not possible to build
a kernel with drm2 and i915kms support.  Adding
"device drm2" and "device i915kms" (the somewhat 
obvious but undocumented guess) to the config file
yields

config: Error: device "drm2" is unknown
config: Error: device "i915kms" is unknown
config: 2 errors
*** Error code 1
