32 bit chroot and ld-linux.so.2

[edwardsa <edwardsa@afrl.kirtland.af.mil>]

I'm installing a 32 bit chroot, following 

http://www.debian-administration.org/articles/356

First, there is a tiny typo under 1.2

-arch should be --arch

Second, it says that I have to put a soft link in /lib to the ld-linux.so.2 in
the chroot. My question is, given that I already have a ld-linux.so.2 in /lib, 
why do I need the link?
