Subject: Better checking of libpcap versions, based in heimdal/builtin.mk. for
 now we are assumming that:

_LIBPCAP_VERSIONS=      0.8.3  0.7.2
_LIBPCAP_0.8.3=         NetBSD-2.99.9* NetBSD-2.99.1[0-9]*
_LIBPCAP_0.7=           NetBSD-1.[56]* NetBSD-2.0*

Users of other platforms should update this list eventually.
