I'm generally against the "add at the bottom of the list" strategy but this file
is already completely unsorted. Just noting this fact, nothing to do.

Yeah, I was not sure if there is any order to follow...

Then this target should not even exist on pure open source checkout.

[ddorwin, 2014/02/12 18:12:52]

The target exists in an external checkout. There is a dummy
widevine_cdm_version_h that is used when branding != "Chrome". This allows us to
control the presence solely with branding = "Chrome" and not need to spread the
logic throughout the GYP files.
