autoconf is so complex that we'll never have behavioural parity with it,
unless we actually rewrite QEMU to use autoconf, but I'm not really
going to advocate that. If there are easy changes we can do to make it
look a little more like autoconf, that's fine, but I wouldn't spend any
non-trivial amount of time on it as there's better uses of our time.
