Why is this necessary if iOS doesn't use the media target?

[servolk, 2015/05/14 22:30:49]

Strictly speaking this is unnecessary for this CL, so I'll remove it for now.
But if we are interested in making media buildable on iOS, then we might still
consider this separate CL https://codereview.chromium.org/1140553004/
