libns and libirs were underlinked (missing libisc, libdns, libisccfg)

Underlinking states for the situation when a binary uses a symbol not provided
by libraries it is directly linked to.  The libns was not linked to libisc and
libdns, and libirs was not linked to libisc, libdns and libisccfg) while using
symbols from these libraries directly.
