You need to use ld to turn it into a dynamic-linkable module.

# example pd makefile;
# -------------------------------------

pd_linux: myextern.pd_linux

.SUFFIXES: .pd_linux

LINUXCFLAGS = -DPD -O2 -funroll-loops -fomit-frame-pointer \
    -Wall -W -Wstrict-prototypes -Werror \
    -Wno-unused -Wno-parentheses -Wno-switch

# location of m_pd.h
PDINC =  -I/path-to-pd/include

        gcc $(CFLAGS) $(LINUXCFLAGS) $(PDINC)   -c *.c
        ld -export_dynamic -shared -o $*.pd_linux *.o -lc
        strip --strip-unneeded $*.pd_linux
        rm $*.o

        rm *.pd_linux
