Huh, I think this is the problem.

So this target supports qfThreadInfo, but then it's returning
an empty thread list...  remote_update_thread_list will delete
threads from GDB's list that are not found in the thread list that
the target reported.  Why is the target reporting that empty list?

See ab970af19746364a4f236bebc238ebb036adc898.

We may be able add a workaround for this.  :-/  Just in case,
can you confirm that the current thread's ptid (inferior_ptid)
is magic_null_ptid?
