nsc: Fix build problem if gtk config store is disabled
gtk config store pulled in libdl.so for us, so things fail
to link of the config store isn't enabled. This makes nsc
pull in libdl itself when its enabled.

# This ns-3 example demonstrates the use of helper functions to ease
# the construction of simulation scenarios.
#
# The simulation topology consists of a mixed wired and wireless
# scenario in which a hierarchical mobility model is used.
#
# The simulation layout consists of N backbone routers interconnected
# by an ad hoc wifi network.
# Each backbone router also has a local 802.11 network and is connected
# to a local LAN. An additional set of(K-1) nodes are connected to
# this backbone. Finally, a local LAN is connected to each router
# on the backbone, with L-1 additional hosts.
#
# The nodes are populated with TCP/IP stacks, and OLSR unicast routing
# on the backbone. An example UDP transfer is shown. The simulator
# be configured to output tcpdumps or traces from different nodes.
