What is the earliest version of Xcode supporting this flag? Do we still want to
support that version of Xcode with gyp?

[justincohen, 2016-02-04 19:06:11]

I believe interface builder custom font support was added in Xcode 6

[justincohen, 2016-02-06 15:46:03]

Looks like desktop also uses this flags.  Here's an example of the latest
desktop ibtool flags we don't use, but I only think we need to add the auto
activate flag:

--module sample_project
--auto-activate-custom-fonts
--target-device mac
--minimum-deployment-target 10.11

PTAL

I'm a bit worried if this breaks running chrome on older OS X's -- does the
auto-activate flag require OS support?

But I suppose if that doesn't work, browser_tests should tell us about this. So
lgtm, but please do a gyp roll before and after landing this so that there's one
roll with just this one revision, and watch the mac testers a bit after landing
the gyp roll with this change.

This broke one of the mac bots, but not the others.  How can I tell what version
of Xcode this is using:

Reverted this for now.
