I don't have any particular experience, but I would recommend you start
with the simplest configuration, using GCC with 32-bit Fortran integers
and the MKL LP64 library. You might also want to test with the Octave
development branch, which has reworked a lot of configure and code
concerning the C/Fortran interface.

I think the following should work

    ./configure \
      --with-blas='-lmkl_gf_lp64 -lmkl_gnu_thread -lmkl_core -liomp5' \
      LDFLAGS='-L/$intel/mkl/lib/intel64 -L/$intel/lib/intel64' \
      LD_LIBRARY_PATH='/$intel/mkl/lib/intel64:/$intel/lib/intel64'

If that doesn't work, then config.log should help you figure out why.

If you do get that working, then try moving on to ILP64.
