I did consider saving the whole big bfd, but rejected that
thought early enough not to write it down.  For once, it would
give a false sense of safety.  The fields that are written today
are written with the same information because of a constant ELF
header interpretation; everything else is in tdata.  Future
fields would generally have to be known about and cleared out
anyway, as with sections.  Saving two fields, as with tdata,
seemed the better approach.

So committed.  Thanks for reviewing.
