mknod is run with fakeroot specifically to avoid permissions errors like this. So either fakeroot is not working properly or there is some bad interaction with btrfs. Can you run mknod with platform-*/sysroot-host/bin/fakeroot to see if it works manually? Try to create a device file on the same filesystem but also on a tmpfs. Do you get the same errors?
