[Build] Provide Linux packages through Open Build Service?

[dwatteau]

openSUSE hosts the Open Build Service, aimed at easing the production and distribution of Linux packages:

For now, ScummTR is still a niche tool that's quick and easy to build, and binaries archives are already provided for the most common systems, but providing real packages would nice for updates, testing more compiler versions and architectures, etc.

But I think that we'd only do this if it remains simple enough to maintain and to use.
