Can you clarify what you mean by "under the NDK 10"? The files in external/clang are used to build clang as part of an Android platform build, not using the NDK.
external/clang/build.py follows the normal sequence for building compilers, which is to use an existing compiler to compile the new source (stage1, sometimes called bootstrapping), followed by using the bootstrapped compiler to compile the new source (stage2). This ensures that the final results are the same no matter which compiler you had when you started. It might help if you explain exactly what you are trying to accomplish. If you are just making changes to clang, you should probably just be using the upstream sources and not the Android platform sources.
