The NDK's own build files:
<ndk>/build/tools/build-cxx-stl.sh
<ndk>/build/cmake/android.toolchain.cmake
for the `c++_static` and `c++_shared` build types add the
`<ndk>/sources/android/support/include` include directory
between the two `<ndk>/sources/cxx-stl/llvm-libc++*` directories.
Re-order our own include directory generation to match.
