__IPHONE_NA was previously defined to 9999, but with
iPhoneOS7.1.sdk it is now undefined. From Availability.h:
"__IPHONE_NA is not defined to a value but is uses as a
token by macros to indicate that the API is unavailable"
This causes Qt to evaluate QT_MAC_PLATFORM_SDK_EQUAL_OR_ABOVE
to true when given __IPHONE_NA as argument. And then the
build will fail.
