Fix #226: Building busybox recurses forever.

Created by: ollieparanoid

If you really want to build busybox, I recommend turning the "timestamp based rebuilds" feature off, otherwise it will build for all architectures all the time whenever you change something, even if you do not increase the version number (that's the idea of that feature). This is, because busybox is a dependency for basiscally everything, so it must get updated whenever you install something, in case it was out of date.

It is easier to simply rename the package.
