OK, great. That’s what I missed.

I’ll get rid of the stray -fobjc-arc in ThirdParty/libwebrtc/libwebrtc.xcodeproj/project.pbxproj for voice_processing_audio_unit.mm as a cleanup step.

Should we also set it in ThirdParty/libwebrtc/Configurations/Base.xcconfig or is there a good argument against doing that? I am considering setting it there and removing it from libwebrtc.xcconfig since eventually all the Base.xcconfig will have it. Or maybe we generally keep all the Base.xcconfig files in sync with each other?
