The way I tend to manage this is I compile everything twice. First
without (linking into a .a using ar and ranlib) and then again with,
linking into a .so

E.g.

SOURCES := foo.c bar.c
OBJECTS := $(patsubst %.c,%.o,$(SOURCES))
SOBJECTS := $(patsubst %.c,%.os,$(SOURCES))
LIB := sponge

lib$(LIB).a: $(OBJECTS)
	ar and ranlib

lib$(LIB).so: $(SOBJECTS)
	gcc with -shared

%.o: %.c
	compile without -fPIC -DPIC

%.os: %.c
	compile with -fPIC -DPIC

I hope that helps
