[Buildroot] BIND 9.5.1 startup fails w/ IPv6 disabled - PATCH to fix built-in root hints

When you guys went to BIND 9.5.1_P2 and P3 for kaminsky and dynamic
update DoS fixes, the ISC folks added compiled-in root hints that get
loaded before any other zones (including user specified root hints) and
when IPv6 is disabled via buildroot option (my setup is this way), BIND
will fail to start complaining that the IPv6 AAAA addresses in the built
in root hints are invalid. The error is right after the server outputs
"setting up root hints" and it complains "2001:503:BA3E::2:30 bad IPv6
My solution is attached as a patch against BIND 9.5.1_P3 that simply
puts #ifdef WANT_IPV6 around the AAAA addrs in the built in table and
now bind starts fine and appears to work fine on an IPv4 only buildroot
It's up to you guys if you want to commit the patch to git. I'm
attaching w/ my Thunderbird e-mail client, hopefully it won't botch the
patch, if so let me know what other ways I can submit the patch.
Thanks -- and hope this helps someone out, I spent too many hours trying
to figure this one out and wanted to at least report it somewhere in
case someone else is googling like mad trying to find an answer.
