Then how do I use get $$2 in the awk expression?
$$LITERAL_DOLLAR$$LITERAL_DOLLAR2? I don't think the second
$$LITERAL_DOLLAR2 will work.

Anyway, sip doesn't seem to support QMAKE_LINK_SHLIB_CMD. So, I created
the attached patch.

With this patch, and you suggestion of $$LITERAL_DOLLAR, and
QMAKE_LINK_SHLIB_CMD set to:
  QMAKE_LINK_SHLIB_CMD    = rm -f objects.o; \
ld -r -o objects.o -bnogc $$LITERAL_DOLLAR{OFILES}; \
rm -f lib.exp; /usr/ccs/bin/nm -BCpg objects.o | \
awk '{ if ((($$LITERAL_DOLLAR$$LITERAL_DOLLAR2 == "T") || ($$LITERAL_DOLLAR$$LITERAL_DOLLAR2 == "D") || ($$LITERAL_DOLLAR$$LITERAL_DOLLAR2 == "B")) && \
(substr($$LITERAL_DOLLAR$$LITERAL_DOLLAR3,1,1) != ".")) { print $$LITERAL_DOLLAR$$LITERAL_DOLLAR3 } }' | sort -u >lib.exp; \
g++ -shared -Wl,-bE:lib.exp -o $$LITERAL_DOLLAR{TARGET} \
$$LITERAL_DOLLAR{LFLAGS} objects.o $$LITERAL_DOLLAR{LIBS}; \
rm objects.o

I get the following in siplib/Makefile:
$(TARGET): $(OFILES)
        @echo '#!' >sip.exp; \
         echo 'initsip' >>sip.exp
        rm -f objects.o; ld -r -o objects.o -bnogc LITERAL_DOLLAR{OFILES}; rm -f lib.exp; /usr/ccs/bin/nm -BCpg objects.o | awk '{ if (((LITERAL_DOLLARLITERAL_DOLLAR2 == "T") || (LITERAL_DOLLARLITERAL_DOLLAR2 == "D") || (LITERAL_DOLLARLITERAL_DOLLAR2 == "B")) && (substr(LITERAL_DOLLARLITERAL_DOLLAR3,1,1) != ".")) { print LITERAL_DOLLARLITERAL_DOLLAR3 } }' | sort -u >lib.exp; g++ -shared -Wl,-bE:lib.exp -o LITERAL_DOLLAR{TARGET} LITERAL_DOLLAR{LFLAGS} objects.o LITERAL_DOLLAR{LIBS}; rm objects.o

If I use $${LITERAL_DOLLAR}, I get the following in siplib/Makefile:
$(TARGET): $(OFILES)
        @echo '#!' >sip.exp; \
         echo 'initsip' >>sip.exp
        rm -f objects.o; ld -r -o objects.o -bnogc ${OFILES}; rm -f lib.exp; /usr/ccs/bin/nm -BCpg objects.o | awk '{ if (((${LITERAL_DOLLAR}2 == "T") || (${LITERAL_DOLLAR}2 == "D") || (${LITERAL_DOLLAR}2 == "B")) && (substr(${LITERAL_DOLLAR}3,1,1) != ".")) { print ${LITERAL_DOLLAR}3 } }' | sort -u >lib.exp; g++ -shared -Wl,-bE:lib.exp -o ${TARGET} ${LFLAGS} objects.o ${LIBS}; rm objects.o
