I don't think this is the way to solve it, because alternatives setup should 
work on build machine when everything is correct in packages. Most probably it 
fails because there is some other package installed which provides some 
program that is present in busybox, but that package doesn't use alternatives 
for (some of) its binaries.

Essentially, this is a bug in a package providing "full" version of the 
binary. You can easily debug those if you add "-x" switch to sh invocation in  
rootfs_ipk.bbclass, you'll see then where it fails in image do_rootfs log.

I've catched some of those in util-linux-ng and will push some patches later 
today.
