#### iPhoneOS/iOS
#
# `xcrun` targets require an Xcode that can determine the correct C compiler via
# `xcrun -sdk iphoneos`. This has been standard in Xcode for a while now - any recent
# Xcode should do.  If the Xcode on the build machine doesn't support this then use
# the legacy targets at the end of this file. These require manual definition of
# environment variables.
