With bfd the rule seems to be that the file is added to the start, no
reordered. So in the above testcase I get

 0000 aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa  ................
 0010 ffffffff ffffffff                    ........

note how the first file shows up twice, once from the script once from
the command line.

Cheers,
Rafael
