Android NDK r16b comes with Android clang version 5.0.300080 (based on LLVM 5.0.300080) Although it claims version 5, it does not support the `-std=c++17` or `-std=c++2a` flags that upstream Clang does. Android NDK r17-beta1 comes with Android (4639204 based on r316199) clang version 6.0.1 that does have the flags.
