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.
