 #   1. Build lib/Support and lib/TableGen, which are used by utils (tblgen).
 #   2. Build utils, which is used by VMCore.
 #   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.
 #
 # When cross-compiling, there are some things (tablegen) that need to
 # be build for the build system first.

 # If "RC_ProjectName" exists in the environment, and its value is

 # "Apple-style" in the comments for more info.  Anything else is a
