llvm_11: Enable build-id when linking libLLVM shared libs

Browse source 
This is used by mesa.drivers (still on LLVM 9) as a cache key. I've
ported that change to LLVM 11 to test it and so that it doesn't get lost
in future versions. Credit for the change goes to David McFarland.
See #93946 for details.
