I don't think this is how precompiled headers are supposed to be added. Found
this:
https://code.google.com/p/chromium/codesearch#chromium/src/build/config/BUILD...

Can you file a bug for GN iOS builds and reference it here? You can assign it to
me and cc kjellander.

I'm not clear on what the bug should be. Could you clarify?

iOS WebRTC GN Build
- Fix prefix headers
- Get it to work

Just a place to accumulate tasks.
