The Xcode project generator doesn't support exclusive builds, and always
runs as the default debug/release config, and with iPhoneOS as the target
platform. This means we need to parameterize the QMAKE_MAC_SDK_* build
settings to depend on the currently active SDK in Xcode, so that the
paths, when used in eg. linker flags, are up to date.
