ios-simulator-xcode-clang failed compiliation with an error of clang++ not found.

build: https://build.chromium.org/p/chromium.mac/builders/ios-simulator-xcode-clang/builds/5114
patch included: https://chromium.googlesource.com/chromium/src/+/4bd91fa47b09c9238cc7d687f94ce64e4e8ea763

That builder seems recovered now, so please mark this issue as WONTFIX if it's not actual problem.
