It's normal that the addresses are not the same, that said, I was expecting the path to be different. The only thing that /etc/ld.so.nohwcap is supposed to change the libraries that are loaded. That said, there is are path for optimized libraries on amd64, so I am not really surprised. I still don't understand the bug...
