Can you make the script emit the usual make-read-only trick at the
top of the generated file?  

See e.g., gdbarch.sh:

 /* *INDENT-OFF* */ /* THIS FILE IS GENERATED -*- buffer-read-only: t -*- */
 /* vi:set ro: */

or make-target-delegates:

 print "/* THIS FILE IS GENERATED -*- buffer-read-only: t -*- */\n";
 print "/* vi:set ro: */\n\n";

Curious, you had this script since 2011?
