It signals that it was built with pymalloc. I believe other letters are 
possible, to indicate other build-time options e.g. debugging compiled 
in, unicode width. The idea, if I understand it correctly, is to allow 
more than one installation of the same version of python with these 
different build-time options, and this is achieved with the namespacing 
symbol ("m" in this case)

IIRC the python binary and all the modules link against the 3.3m.so and 
the "libpython3.so" is a tiny stub that does nothing.

I assume you are using python3-config [--cflags|--libs] to get the 
various compiler flags back; I guess if you want to permit people to 
build against >1 installed python, you will want a:

--with-pyconfig

...and they can always run:

./configure --with-pyconfig=/usr/bin/python3.3mabceud-config
