Without this option, the linker fails to link any library that uses std::future. The error points some undefined references, like std::__future_base::_Result_base.

For example, it fails to link rustc because llvm 4.0 uses std::future.

Here is a script to reproduce the problem. It is necessary to have ndk installed and the android gcc compilers on path.
