Where is this from? Can't find anything corresponding in the gyp files.

[ossu, 2016/07/07 12:42:42]

I took them from the voice_engine target above.. I guess the base flags for GYP
builds don't include these checks, whereas they do when building with GN.
Without 'em, I get roughly a million warnings about style issues.
