I tried objcopy (it was my first thought), for one reason or another it
didn't work (internal BFD error something). Reportedly ECOFF is belly-up
in current GNU binutils - at least it is what I heard.

My input is elf32-tradbigmips. So I entirely don't care for binutils'
ECOFF anymore, and I consider this a good thing. As I said, objcopy didn't
work at all. Fixing BFD is not my job (it's a monster of Frankensteinian
proportions), I think that it is actually much easier to write my own
converter (well, I did it, and it works - except that funny HI/LO mismatch
I'm going to work around).
