Fail to run iperf3 on osv

[asias]

We are missing some symbols.

[asias@hjpc osv]$ scripts/check-libcfunc-avail.sh release apps/iperf3/libiperf.so.0.0.0
__h_errno_location not found
getpeername not found
system not found
sched_setaffinity not found
sendfile not found
hstrerror not found
[asias@hjpc osv]$ scripts/check-libcfunc-avail.sh release apps/iperf3/iperf3.so
daemon not found

The iperf3 module for osv is here: https://github.com/asias/osv-apps/tree/iperf3

[asias]

With getpeername and __h_errno_location implemented, we are able to run iperf3 now. But another issue occurred.

We can definitely run iperf3 now on OSv at least as of cloudius-systems/osv-apps@1807b4d. Closing it.
