hosts_ctl() should be supplied by the libwrap library; you
must be building with USE_TCP_WRAPPERS defined but have
not included the library. The lines in the Makefile just
below USE_TCP_WRAPPERS have comments implying that the need
for an explicit mention of the library varies across platforms.
Few people actually use tcpwrappers these days, I think; full
firewalling with iptables or similar is more common.
