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.
