Am I doing something wrong here? how do I get it to build for aarch64?

I am trying to build a multiarch package (ITP #1055706) for debian on a raspberry pi. The package builds fine, however, there is a lintian error like so: when I run dpkg --print-architecture it says arm64 but when I run the command arch it says aarch64.
