Jami fails to compile on pinephone (aarch64-linux-gnu)

Hello,

trying to install Jami on Pinephone I've tried to follow the procedure described on https://github.com/savoirfairelinux/ring-project

Unfortunately it fails at ./make-ring.py --install --global-install with following:

checking whether make sets $(MAKE)... yes
checking build system type... Invalid configuration `aarch64-linux-gnu': machine `aarch64' not recognized
configure: error: /bin/bash ./config.sub aarch64-linux-gnu failed
../../contrib/src/dbus-cpp/rules.mak:31: recipe for target '.dbus-cpp' failed
make: *** [.dbus-cpp] Error 1
Traceback (most recent call last):
  File "./make-ring.py", line 528, in <module>
    main()
  File "./make-ring.py", line 515, in main
    run_install(parsed_args)
  File "./make-ring.py", line 322, in run_install
    return subprocess.run(["./scripts/install.sh"] + install_args, env=environ, check=True)
  File "/usr/lib/python3.5/subprocess.py", line 708, in run
    output=stdout, stderr=stderr)
subprocess.CalledProcessError: Command '['./scripts/install.sh', '-p', '4', '-g', '-c', 'client-gnome']' returned non-zero exit status 2

Unfortunately I don't really know whether this is expected (and Jami just doesn't support this system type) or it's a real issue or whether there's any workaround to try.

The system I've tried to built it on is Ubuntu touch:
