Chris Bieneman cbccd8ddf5 Checking if TARGET_OS_IPHONE is defined isn't good enough for 10.7 and earlier.
Older versions of the TargetConditionals header always defined TARGET_OS_IPHONE to something (0 or 1), so we need to test not only for the existence but also if it is 1.

This resolves PR22631.
