Not sure what this was for. mmoss added it in
https://codereview.chromium.org/256020 , it looks strange to me.

I don't know much about xcode, so I probably either got those settings from
another dev or migrated it from some other config (maybe from the scons days?).
If nobody else knows why it's needed, and it works without it, then LGTM.
