I reckon the original plan was to make the steps in the reverse order so
that there's no pressure from outstanding releases to get the GIT tree in
order, which I found reasonable -- what was the rationale behind changing
the plan? It has somehow escaped me (a list archive reference will do).

That sounds like a plan, thanks, and should be doable with a reasonable
effort -- the changes really needed by GDB are the addition of
_bfd_mips_elf_get_synthetic_symtab to bfd/elfxx-mips.c, its wiring in
bfd/elf32-mips.c, and then small self-contained pieces in opcodes/ and of
course gdb/. I'll have a look at it and let you know when I'm ready with
a backport.
BTW, please note that the old format remains supported and produced for
standard MIPS and, in some cases, mixed-mode binaries, so it's not like
it's going away or something.
