musl does not provide these constants in <netinet/tcp.h>
Signed-off-by: Felix Janda <felix.janda@xxxxxxxxx>

It is not clear to me whether these constants belong to iptables or musl's
netinet/tcp.h. So this message is CC'd to the musl list.
In the code indexed by debian code search I have only found iptables and
traceroute using them without having a local copy of tcp.h.
Note that this patch is incomplete: utils/nfsynproxy.c uses them as well
