Thanks for your help, i found the problem.
We have a Dell Precision 370 with Pentium D. This processor supports Intels
EM64T architecture, that means he can 64-bit. Now it seems Suse has
installed the 64-bit system automaticly.
I tried to give the gcc/g++ the flat -m32 with
--with-cxxflags=-m32 and --with-cflags=-m32, but there was an error, how is
the correct syntax?
Kind Regards, Sebastian

According to config.log, you are mixing 64-bit and 32-bit objects. If
you intend to build a 32-bit lam-mpi, using ifort and gcc/g++, you must
pass the -m32 flag to gcc/g++. If you intend a 64-bit lam-mpi, you
must set your Intel compiler environment to the 64-bit compiler,
/opt/intel_fce_80/bin/ifort or /opt/intel/fce/9.0/bin/ifort, along with
the companion LD_LIBRARY_PATH.
