#   1. Build lib/System and lib/Support, which are used by utils (tblgen).

#   3. Build VMCore, which builds the Intrinsics.inc file used by libs.
#   4. Build libs, which are needed by llvm-config.
#   5. Build llvm-config, which determines inter-lib dependencies for tools.
#   6. Build tools, runtime, docs.
