Improve procedure to construct best link command for macOS platform

Browse Source 
As discussed between Matthias, Albrecht and Manolo, the best procedure is
- use MAC_OS_X_VERSION_MAX_ALLOWED but not __MAC_OS_X_VERSION_MAX_ALLOWED;
- compile helper file CMake /macOSMaxAllowed.c to detect whether the SDK in use
is in version above a given threshold version number;
- based upon the result of this check, decide to weakly link or not a given framework.
