That's the case indeed, and afaik it's not the only case.
I talked a bit with my peers, and there is a consensus on our side that
thing should not be relying on `uname` to detect the host architecture.
Indeed before the stretch release we were actively testing varying
kernel on the i386 builds by using an amd64 kernel and filed bugs for
them.

Please make your package not rely on uname.
