I got 'guix-build-coordinator-agent-only' built now, running it (with
--help) will segfault though..


How to run it to connect to the coordinator?

Also my net speed to ci/bordeaux is unuseable, i guess this will prevent
use my sbc as a build agent for the official build farm?

A friend (Z572 from #guixcn) of mime had setup a coordinator /
substitute server of riscv64 (running guix system) at
https://cache.z572.online.  I tried connect to it with:

```
guix-build-coordinator-agent  \
  --uuid=XXXX \
  --password=XXXX \
  --coordinator=https://cache.z572.online/agent \
  --substitute-urls='https://cache.z572.online'
```

but got:
```
locale is C.UTF-8
(gnutls version: 3.7.7, guix version: 1.4.0-6.dc5430c)

Maybe my arguments or his endpoint is wrong.


Help need, thank you!
