[CMake] CMAKE_<LANG>_FLAGS added to link rule

Thanks. I understand it a bit better now, but I'm not sure how other compilers implement this. Fortunately I can redefine the way cmake generates rules for the Fortran linkstage, so I'm a happy camper. Hopefully when I'm done the spirit of cmake is still alive and we have a somewhat crossplatform implementation of our build system. I need to find some more resources on how to handle special cases without manhandling cmake. Well, I digress.
