Description: SCTP workaround for kfreebsd
 Freebsd has SCTP in the kernel but no sctp library is available,
 then iperf3 fails to compile because the lack of the library.
 .
 This patch moves the search for the library before kernel headers checks
 and of course it should be removed once Freebsd gets the library.
