Correct way to get architecture of cpu

[MrMeshok]

In Debian I maintain 2 packages which uses host_machine.cpu_family() to create configuration files and this causes problems on armel and armhf architectures. Because they both have cpu_family as arm and this creates conflicts if you tried to install both packages simultaneously. My first thought was to just use host_machine.cpu() but maybe there is more robust way?

Theses 2 packages are:
