I guess these aren't used on Linux, but what about rs6000-nat.c?  Those
are the only non-BSD users of inf_ptrace_target that I can see.

I'm not a big fan of the current code, because makes methods conditional
on this define.  It would be better I guess to have an intermediate
subclass for this situation.  That would make it clear what code does or
does not rely on this.

You don't have to do that, but I don't think we can put this in without
knowing about the rs6000-nat case.
