Especially since software rendering (swrast in mesa) uses LLVM these
days (llvmpipe), having mesa continue to build is useful, otherwise it
can get caught up in transitions and block a lot of downstream software
from building (cmake -> qt -> mesa is an annoying build dependency
chain that quickly becomes problematic).
