[Ipopt] Using ipopt with PARDISO

Intel's MKL consists of BLAS/LAPACK and mkl_solver (= Pardiso).

It is known, that the MKL-Pardiso don't work (I wonder if this is still
true for the newest MKL) but you can use MKL_BLAS/LAPACK with the
"academic Pardiso".

The BLAS shouldn't make a difference. But at least for gcc 4.3 on 
Linux 64bit
I was not able to use MA27 with MKL BLAS/LAPACK and I also was not able
to link with the "academic Pardiso".
