A revert of this CL (patchset #2 id:140001) has been created in
https://codereview.webrtc.org/2343083002/ by nisse@webrtc.org.

The reason for reverting is: I was too impatient; this made android builds fail
instead. See
https://build.chromium.org/p/client.webrtc/builders/Linux32%20ARM/builds/585/...
