Support arch derivate: alarm

[entropicdrifter]

It would be nice to use this on my M1 Mac running Asahi Arch. That's all. I tried to build it anyways and while the build succeeded no problem, the program itself crashes with the following error:

It seems to me it might be fixable with a config change? Just guessing based on the log.

Its not so much that it is a different architecture, as it is a different, though closely related, distro.
That means different repos to pull the base data from. As both are arch-based no structural change.
i had anticipated this usecase and put the distro name into the url so multiple distros can be supported on the same server even, but i have not done the adaptation.

one thing that is very useful to have is an archive mirror that has all historic versions of all packages for a distro, do you know of one for alarm? it is not strictly required.

As far as my personal research has shown, the only active archive mirror for ALARM is this one: http://tardis.tiny-vps.com/aarm/

I did also find this fork of the archiving tools, if you or anyone else is interested in building your own archive/mirror:

thank you for the research, i will probably add alarm-support in time, though likely not very soon
