The latest upstream merge for libsanitizer introduces code that makes use of some macro values that are not available in SDKs for versions of Darwin <= 15 (macOS 10.11). Add definitions for these where they are not present. libsanitizer/ChangeLog: * sanitizer_common/sanitizer_mac.h: Ensure that TARGET_OS_ macros are defined where the macOS SDK does not contain them. (TARGET_OS_OSX, TARGET_OS_IOS, TARGET_OS_TV, TARGET_OS_WATCH): Define where needed.
