[CMake] Patch CMake for Mac static library creation

[Belcourt, K. Noel]

Hi,

I'm on Mac OSX 10.5.8 with Intel 12.x compilers and CMake version  
2.8.3.  CMake doesn't seem to add the -c option to the ranlib command  
to include common symbols into the library table of contents.  Here's  
the documentation for Apple's ranlib.

        -c     Include  common  symbols  as  definitions with respect  
to the table of contents.  This is seldom the intended behavior for
               linking from a library, as it forces the linking of a  
library member just because it uses an uninitialized global that  is
               undefined  at  that  point in the linking.  This option  
is included only because this was the original behavior of ranlib.
               This option is not the default.

This behavior is necessary if you have Fortran 90 modules that define  
data but that don't contain any code (or contains code that isn't  
called).  Can -c be added by default when creating static Fortran  
libraries on the Mac using ranlib?

Thanks.
