In most other places we put everything in sources and then conditionally remove
it. There is already  if (is_nacl) block below.

[Hzj_jie, 2017/04/05 20:52:16]

Done.

[Sergey Ulanov, 2017/04/03 23:50:21]

It's not implemented for Android either. Do we need any of this stuff outside of
remoting/host? If not, maybe move it to host directory?

[Hzj_jie, 2017/04/05 20:52:16]

Done.
