Please let me know that which try-bot should I check for official build when
re-landing this patch.

Thanks; sorry for the trouble. Looks like somehow we're pulling in multiple
copies of the source_set() which results in double linking. I don't see anything
wrong with the //media/formats CL, so I think it's some mulitplicative affect
with the media/filters one. Will see about figuring out what's going on.
