MPICH2 provides a bunch of libraries other than libmpich.a, so directly
using gcc with -lmpich is not safe. You should use the mpicc/mpif90
wrappers instead: Try this:

$ ./configure --prefix=/usr/local/mcnpx \
	--with-FC=mpif90 \
	--with-CC=mpicc \
	--host=i686-pc-linux \
	--with-FFLAGS="-DUNIX=1 -DLINUX=1 -DG95=1" \
	--with-CFLAGS="-DUNIX=1 -DLINUX=1"
