The latter, of course, is somewhat better, but that's not what I'm saying.
I'm saying that if you have write conditional logic for target = build case,
and you have a cross-compiler, then things will just work.
Autoconf might be a help for writing the conditionals, but it's completely
independent from handling target != build case.
