Here it's looking for main, which it shouldn't be doing because you are 
building a shared library with no function named main in it. Did you set 
the current make target to be pd_linux? The first line of the makefile I 
used is:
current: pd_linux
...otherwise it may be trying to build an OSX version.
The linux part of the makefile I used has:
# ----------------------- LINUX i386 -----------------------

pd_linux: $(NAME).pd_linux



LINUXCFLAGS = -DPD -DUNIX -O2 -funroll-loops -fomit-frame-pointer \
     -Wall -W -Wshadow \
     -Wno-unused -Wno-parentheses -Wno-switch

# where is your m_pd.h ???
LINUXINCLUDE =  -I../../build/include

LINUXEXTERNALS = htmsocket.o OSC-pattern-match.o sendOSC.o dumpOSC.o 

         cc -O2 -Wall -DPD -fPIC $(LINUXCFLAGS) $(LINUXINCLUDE) -c *.c
         ld -export_dynamic  -shared -o $*.pd_linux $*.o 
         strip --strip-unneeded $*.pd_linux

# ----------------------------------------------------------

...notice the -export_dynamic and -shared flags.
...but maybe you have something else?
