I used configure sgi_mips f90 mpi and this is my config.h.
-------------------- config.h -------------------------------
#!/bin/csh -f
setenv PREPROCFLAGS "-DMPI -DDIRFRC_VECT_OPT"
setenv CPP /lib/cpp

# SGI specific ``code'' to recognize the type of machine and its environment
set cpuarch = ` hinv -t cpu | awk ' { print $3 } ' | head -1 `

# Do we have the FFT libraries in libcomplib.sgimath.a?
if ( -e /usr/lib/libcomplib.sgimath.a | \
     -e /usr/lib32/mips4/libcomplib.sgimath.a | \
     -e /usr/lib32/mips4/libcomplib.sgimath.so | \
     -e /usr/lib64/mips4/libcomplib.sgimath.a ) then
     setenv PREPROCFLAGS "$PREPROCFLAGS -DSGIFFT"
     set sgimathlib = "-lcomplib.sgimath "
endif

if ( $cpuarch == R8000) then
  set mipsflag = "-mips4 -n32 -r8000 "
  set nflags = (-WK,-dr=AKC -OPT:cis=off:roundoff=3:IEEE_arithmetic=3
-SWP:strict_ivdep=OFF -TENV:X=3 )
else
  if ($cpuarch == R10000) then
    set mipsflag = -r10000
  else if ($cpuarch == R12000) then
    set mipsflag = -r10000
  else if ($cpuarch == R14000) then
    set mipsflag = -r14000
  else if ($cpuarch == R16000) then
    set mipsflag = -r16000
  else
    echo "Error - unsupported SGI CPU type $cpuarch!"
    exit(1)
  endif
  set mipsflag = "$mipsflag -mips4 -n32"
  set nflags = ( -OPT:roundoff=3:IEEE_arithmetic=3:fast_bit_intrinsics=ON )
endif

setenv CC "cc $mipsflag"
setenv CFLAGS "-O3 $nflags "

setenv OPT_LO "f90 -nocpp $mipsflag -c -O1 -old_rl $nflags "
setenv OPT_MED "f90 -nocpp $mipsflag -c -O3 -old_rl $nflags "
setenv OPT_HI "f90 -nocpp $mipsflag -c -O3 -old_rl $nflags "

setenv LOAD "f90 $mipsflag "
setenv LOADLIB " $sgimathlib -lfastm -lmpi"
