Initial provisioning was already done in build_ios_libs.sh to support building the WebRTC framework or static library for iOS (tvOS, watchOS) with bitcode. Still, the actual build configuration would need to be modified for each and every part of the build, including 3rd-party libs. Thus, doing that more universally, at the build/config level, would be desirable – and actually necessary to provide the intended support. The patch for enhancing the Chromium build configs with that specific option was landed in https://codereview.chromium.org/2631573002 NOTRY=True BUG=webrtc:5085 Review-Url: https://codereview.webrtc.org/2633643003 Cr-Commit-Position: refs/heads/master@{#16193}
