there seems to be a typo in /source4/dns_server/wscript_build:
....
....
# a bind9 dlz module giving access to the Samba DNS SAM
bld.SAMBA_LIBRARY('dlz_bind9',
                  source='dlz_bind9.c',
                  cflags='-DBIND_VERSION_9_8',
                  private_library=True,
                  link_name='modules/bind9/dlz_bind9.so',
                  realname='dlz_bind9.so',
                  install_path='${MODULESDIR}/bind9',
                  deps='samba-hostconfig samdb gensec popt')

bld.SAMBA_LIBRARY('dlz_bind9_9',
                  source='dlz_bind9.c',
                  cflags='-DBIND_VERSION_9_9',
                  private_library=True,
                  link_name='modules/bind9/dlz_bind9_9.so',
-                  realname='dlz_bind9.so',
+                  realname='dlz_bind9_9.so',
                  install_path='${MODULESDIR}/bind9',
                  deps='samba-hostconfig samdb gensec popt')
----

I'm no waf expert, but with that change, both dynlibs are build
and then installed during 'make install':
   ./lib/bind9/dlz_bind9.so
   ./lib/bind9/dlz_bind9_9.so

The right one must then be "selected" manually
in the s4 generated ./private/named.conf file
(installed during a new provision step...)
