[PyQt] How to insert literal $ in QMAKE_LINK_SHLIB_CMD sip spec files

[Albert Chin]

How do I insert a literal $ in QMAKE_LINK_SHLIB_CMD for sip spec files?
What I really want is the following for specs/aix-g++:
  QMAKE_LINK_SHLIB_CMD    = rm -f objects.o; \
          ld -r -o objects.o -bnogc $(OFILES); \
          rm -f lib.exp; /usr/ccs/bin/nm -BCpg objects.o | \
          awk '{ if ((($$2 == "T") || ($$2 == "D") || ($$2 == "B")) && \
          (substr($$3,1,1) != ".")) { print $$3 } }' | sort -u >lib.exp; \
          g++ -shared -Wl,-bE:lib.exp -o $(TARGET) $(LFLAGS) \
          objects.o $(LIBS); rm objects.o
