The buildworld is doing libclang compiles now:

# sysctl dev.aw_sid.0.ths-calib dev.aw_thermal
dev.aw_sid.0.ths-calib: 820788078307
dev.aw_thermal.0.gpu2: 27C
dev.aw_thermal.0.gpu1: 28C
dev.aw_thermal.0.cpu: 30C
dev.aw_thermal.0.%parent: simplebus0
dev.aw_thermal.0.%pnpinfo: name=thermal_sensor at 1c25000 compat=allwinner,sun50i-a64-ths
dev.aw_thermal.0.%location: 
dev.aw_thermal.0.%driver: aw_thermal
dev.aw_thermal.0.%desc: Allwinner Thermal Sensor Controller
dev.aw_thermal.%parent:

It will be a notable before the buildworld completes
(if it finishes normally).
