Yeah, I recall you mentioning this. I don't want to make a change that's
going to potentially break in the future because of upstream. I'm
inclined to sit on this bit of patchwork and push it to my working
branch until busybox figures out wtf it is they're going to mangle next.
We're not making any radical changes here -- what we have right now
works, and this is really only to avoid a few forks at bootstrap.

Regardless, you're right that looping over the included applet list is a
better way to do this. I think that it's also advantageous because then
we can symlink everything into /bin and let user overrides take place in
/usr, without having to involve /usr/local (which is a bit odd, imo).
