What dos RHEL5 ship? That's usually our benchmark for
"oldest thing we need to support". Ubuntu 10.04 LTS (lucid)
and Debian oldstable (squeeze) both ship something more
recent than 7.16, so we're OK there.

We should probably update the configure test to check for
curl_multi_socket_action() rather than curl_multi_setopt().
