Modified check_ping to handle IPv6 as well as IPv4 ICMP checks using the

PING6_COMMAND determined during the configure script execution. As
USE_IPV6 may be defined and PING6_COMMAND is not defined if there is not
IPv6 TCP stack available when configure is run I condition it off
PING6_COMMAND existing to remove build errors for being undefined.
