  Enable creation of large response file on z/OS

Most text processing commands (eg. grep, awk) have a maximum line length limit on z/OS.  The current method of using cc -E & grep fails on z/OS because of this limit.  I'm changing the command to create the long line in the response file to use python.  This avoids the possibility of any tools blocking the generation of the large response file.  This also eliminates the need for the extra file.
