This is badly conceived, unfortunately. This conditional disables ping6
at least for OpenBSD, GNU/kFreeBSD, and OpenSolaris.

  * Solaris has IPV6_RECVHOPLIMIT, but lacks IPV6_2292HOPLIMIT.

  * OpenBSD, FreeBSD, and kFreeBSD all have IPV6_RECVHOPLIMIT,
    as well as IPV6_2292HOPLIMIT, but the latter is reserved
    for kernel code, unless manually specified.

Thus BSD and Solaris will presently fail in building ping6
by default, in spite of our source being fully functional
also for them.
