[pve-devel] [PATCH v2 qemu] debian/rules: added placeholder for additional targets

[Geert Stappers]

Default behaviour of QEMU is to build for all system targets.
"system target" is a CPU architecture.
Proxmox builds only for the host arch, which boils down to only allowing x86.
So also only allowing x86 guests.

For supporting other CPU architectures, needs the target list to be expanded.

How to expand the target list is not obvious.
Questions arise which list seperator to use.
With this "placeholder" is documented how to add additional targets.

No real code change, just preparing for build change.
