Ok. I found the solution. Thanks to Carl Laird for the pointer. We need to
include the library for gomp in the configure command. I used:

 ./configure --prefix=$HOME/octave-src/ipopt370/install ADD_CXXFLAGS="-fPIC
-fexceptions" ADD_CFLAGS="-fPIC -fexceptions" ADD_FFLAGS="-fPIC
-fexceptions" --with-pardiso="-fopenmp
$HOME/octave-src/ipopt370/libpardiso_GNU43_AMD64_INT64_P.so"
ADD_LIBS="-L/usr/lib/gcc/x86_64-linux-gnu/4.3 -lgomp"

Now Pardiso works.
