Many of the "extra" libraries are ISC-provided and therefore not
exactly "external".  Looking at the Debian package info, it seems that
these libraries are in fact part of the bind9 source.

$ apt-cache show liblwres1 libdns5 libisc4 libisccc0 libisccfg0 \
  | grep ^Source | uniq
Source: bind9

Specifically:

        liblwres.so.1 => /usr/lib/liblwres.so.1 (0x40026000)
        libdns.so.5 => /usr/lib/libdns.so.5 (0x40034000)
        libisccfg.so.0 => /usr/lib/libisccfg.so.0 (0x401e4000)
        libisccc.so.0 => /usr/lib/libisccc.so.0 (0x401f3000)
        libisc.so.4 => /usr/lib/libisc.so.4 (0x401fb000)

The rest of the libraries are part of glibc.
