Detect Fortran ABI Information Implement Fortran 32/64-bit ABI detection on some platforms. We need to set CMAKE_SIZEOF_VOID_P correctly in Fortran-only projects so that the find_library() command knows whether to look for 64-bit binaries. We also detect ELF binaries to enable RPATH replacement. See issue #10119.

Fortran: Detect pointer size on Intel archs with PGI (#14870) The PGI compiler does not define __SIZEOF_POINTER__ so use the __x86_64__ or __i386__ CPU macros to select a pointer size instead.

Fortran: Detect pointer size in gfortran on MinGW Use __SIZEOF_POINTER__ which the GNU Fortran compiler defines at least on 64-bit MinGW. Assume default size 4 on MinGW if gfortran does not define the size.

Fortran: Improve pointer size detection in gfortran on MinGW In commit ecd84147 (Fortran: Detect pointer size in gfortran on MinGW, 2011-11-29) we started testing for __SIZEOF_POINTER__ but not all GNU Fortran compilers define this. Check also for __SIZEOF_SIZE_T__ which at least one version of gfortran defines without also defining __SIZEOF_POINTER__.
