[PATCH qemu-server v2 4/8] cpu config: introduce module-wide $host_arch variable

[Fiona Ebner <f.ebner@proxmox.com>]

It cannot change while the module is loaded. Also, commit "cpu config:
support aarch64 CPU models" will use the host arch as a hash key,
which is cleaner if no additional function call is required.
