This patch is about object files only, so doesn't all of this belong in the
next patch?

What about x86-64 at the very least? That's the most common target nowadays,
i.e. also the one with the pest chances of catching regressions early. Also
while I realize that there are several uses of i*86-* there already, I think
that's a little too broad. Can I talk you into using i?86-* instead?
