I had to fix this error, but otherwise it built and runs (probably a
musl vs glibc thing):

I can connect to the network, enter pin code, get sim card status, etc.
I still don't seem to get ofono notifications (like signal strength) on
time at all, though. If I wait for a few minutes, and then run the
send-sms script, I get a load of ofono signal strength updates, all at
once. Those are probably being queued up somewhere and not received
(note the timestamps):

Pavel, are you seeing this on your ofono fork/branch too?
I will add this ofono to the -devel repo today, since it's easy to build
for me. Happy to try to build Pavel's ofono too, if you think the repos
diverge significantly (it's not quite clear to me at this point).
Cheers,
Merlijn
