'recent' updates break USE_INET6="no" build

[Iain Hibbert <plunky%rya-online.net@localhost>]

Hi,

I think the recent update of crypto/dist/heimdal v1.1 may have broken
building with USE_INET6="no" (in /etc/mk.conf)

The breakage occurs when "cvs" is being linked because of no "in6addr_any"
symbol. That would normally be defined in libc, and is referenced by
libkrb5/addr_families.c which is should be excluded by "#ifdef
HAVE_INET6".

The lib/libkrb5/Makefile seems to define that only when (USE_INET6 != "no") but
I'm not sure why that doesn't get passed down.

any clues?
