Sending this out for review now, though it should probably wait until Monday if
the change sticks.

It's also not a complete fix for the components build; we'll want to either
change the forwarding openssl.gyp to be "type": "none" or switch WebRTC over to
pointing straight at boringssl.gyp.

LGTM.

Note the android_{clang_}dbg failures. Hopefully that's just because of a
different base revision.
