Subject: [PATCH 2/5] Simplify cross-compilation. Don't use native-compiled
llvm-config.
Note: AddLLVM.cmake does not expose the LLVM source directory.
So if you want to run the test suite, you need to either:
1) set LLVM_MAIN_SRC_DIR explicitly (to find lit.py)
2) change AddLLVM.cmake to point to an installed 'lit'.
3) add_subdirectory(compiler-rt/test) from clang instead of compiler-rt.
