  Hmm, but that was for the .sbss section, which is a target-optional extra
section; the main .bss section is common to all targets, created in
as.c/perform_an_assembly_pass, and would have the seg_info bss flag set already.

  You'll probably have to dive down into bfd to figure this one out.  This is
an ELF target isn't it?  In which case I'm not going to be able to be a whole
lot of help.
