Currently soliciting opinion from binutils mailing list about the

loadfile() is now fixed (as much as I think it should be fixed). elf32
and elf64 handling are now explicit, and they byte-swap as necessary
when used in a non-_STANDALONE environment (e.g. installboot(8)).
I don't think it's worth the effort to fix the a.out and ECOFF loadfile()
loaders. We should be spending the effort getting ELF everywhere, relegating
the a.out and ECOFF loaders to backwards-compatibility native tools.

This is logically part of the nlist(3)-elimination project -- but go ahead
and leave it as a separate bullet, if you like.
Something to add:
BFD- and loadfile()-using dbsym(8). Simon Burge has this
partially done, and I suspect he'll finish it unless he
wants to hand it off to me.
