        i once tried to build GNU toolchain with fully-featured BFD
        (handles any binary), instead of single-platform BFD.  the attempt
        end up as failure due to the bug in BFD wrt 32bit/64bit handling.
        once i enable BFD code for 64bit CPU, all pointers become 64bit,
        and BFD code for 32bit CPU goes crazy.
