#   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
