Please set FC=gfortran
Since you have set FC=/opt/mpich2/gnu/bin/mpif90, the NWChem makefile structure gets confused and tries the -i8 option.
Please set
FC=gfortran
since gfortran is recognized by the NWChem makefile structure.

need to extract MPI definitions from
Your MPI_LIB and LIBMPI definitions are not setup correctily.
Some standard definitions are described at

http://nwchemgit.github.io/index.php/Compiling_NWChem#Setting_up_the_proper_environment_vari...

If this is not of help, please run the command

/opt/mpich2/gnu/bin/mpif90 -show

and use the output to define MPI_LIB and LIBMPI.

Please let me know if you need more assistance
