Android: Select the STL type for NDK builds
Populate standard include directories and link libraries for the platform. Select the STL corresponding to CMAKE_ANDROID_STL_TYPE and matching the current ABI and toolchain to be used. Refer to the NDK sources/cxx-stl/*/Android.mk files for the needed file locations.
