Here's the Makefile I use:

-- CUT HERE --
CC=gcc
CFLAGS=-fPIC -O2 -Wall -Werror -pedantic
CPPFLAGS=-I.
LDFLAGS=-x --shared -lpam

OUT=pam_test.so

all:    $(OUT)

%.so: %.o
	ld $(LDFLAGS) -o $@ $<

clean:
	rm -f *.o $(OUT)

install:
	install -s -o0 -g0 -m755 $(OUT) /lib/security
-- CUT HERE --

This would cause two commands to be executed:
gcc -fPIC -O2 -Wall -Werror -pedantic -I.  -c -o pam_test.o pam_test.c
ld -x --shared -lpam -o pam_test.so pam_test.o

Presumably, you have an appropriate #include in pam_test.c for
pam_test.h...
