I'm sorry for false alarm, the last sentence is the key. In webOS builds
we have filter for staging static libraries (to prevent accidental usage
of static library with unwanted license in our components) and of course
I forgot to whitelist these llvm libraries used by mesa.
Once staged in sysroot mesa builds with gallium-llvm again OK, so this
change is good to go.
