Uses wrong define to change array size

stream-scaling uses -DN=... to change the array size. This results in:

*****  WARNING: ******
  It appears that you set the preprocessor variable N when compiling this code.
  This version of the code uses the preprocesor variable STREAM_ARRAY_SIZE to control the array size
  Reverting to default value of STREAM_ARRAY_SIZE=10000000
*****  WARNING: ******

And doesn't work. It needs to be changed to -DSTREAM_ARRAY_SIZE=...
