Thanks. I realize only now that I should also update gas/doc/ in
patch 2. I'll assume that's fine to slip in, for only being
consistent.

I have to admit that I wasn't sure how far to go: Removing support
from ld certainly makes sense (and I'll see to find time), but
wouldn't it be reasonable to keep the minimal support there is in
binutils/?

I've noticed there's one piece of special casing behavior for L1OM
in i386-dis.c. I'd be inclined to drop that too - thoughts?
