There's something weird going on here. mkoctfile from the Debian package
calls g++ with its full path. Additionally, we don't pass the "-m32"
flag to the compiler. For comparision, the output in my chroot:

# mkoctfile -v uitest.cc 
/usr/bin/g++ -c -fPIC -I/usr/include/octave-2.9.7
-I/usr/include/octave-2.9.7/octave -O2 uitest.cc -o uitest.o
/usr/bin/g++ -shared -Wl,-Bsymbolic -o uitest.oct uitest.o
-L/usr/lib/octave-2.9.7 -loctinterp -loctave -lcruft -s -llapack-3
-lblas-3 -lfftw3 -lreadline -lncurses -ldl -lhdf5 -lz -lm
-L/usr/lib/gcc/x86_64-linux-gnu/4.1.2/../../../../lib64 -L/lib/../lib64
-L/usr/lib/../lib64 -lhdf5 -lz -lgfortranbegin -lgfortran -lm -lgcc_s

Is it possible that you have a local installation of Octave coming in
the way (i.e., that mkoctfile is not /usr/bin/mkoctfile)? Or that you
have a mixed 32/64 bit environment?
