Yeah.  I've just found this out the long hard way.

I've been adding a collect-sections-to-make-data kind of thing to
m68kcoff (it does the same sort of job as .rel.sdata in mipsecoff:
loadtime relocations for data sections).  My data is 10 byte records.
It seems I have three choices:

1.  Admit defeat and pad each record to 12 bytes.
2.  Override coff_new_section_hook like in coff-sh.c.
3.  Add yet another special case for my little section to
    coff_new_section_hook in coffcode.h.

Is there any advice as to the "right way"?  At the moment I'm using #2,
but it feels like overkill, and, for a bfd neophyte like me, it took ages
to figure out.  I feel like maybe the "spirit of coff" is #1.

(Also BTW:

I also found out the long hard way that coff_set_alignment_hook only
applies when reading in a bfd file.  If you want special alignment
handling for sections created in the linker, I think you want
coff_new_section_hook.  But maybe this isn't your situation.)
