How to disable frozen_module during build

I added some operations for my research in gcmodule in gc_collect_main() that causes error during build:

Python/frozen_modules/site.h:site \
Python/frozen_modules/stat.h:stat \
Python/frozen_modules/importlib.util.h:importlib.util \
Python/frozen_modules/importlib.machinery.h:importlib.machinery \
Python/frozen_modules/runpy.h:runpy \
Python/frozen_modules/__hello__.h:__hello__ \
Python/frozen_modules/__phello__.h:__phello__ \
Python/frozen_modules/__phello__.ham.h:__phello__.ham \
Python/frozen_modules/__phello__.ham.eggs.h:__phello__.ham.eggs \
Python/frozen_modules/__phello__.spam.h:__phello__.spam \
Python/frozen_modules/frozen_only.h:frozen_only \

What I added, when placed outside gc_collect_main(), and called after a successful build has no problem (eg., from PyThread_start_new_thread()). I’m positive that I did not mess up the internal gc module state, garbage list, or anything like that.
Here the problem is clearly from building frozen_modules. But it’s hard to pinpoint purely based on this. Thus, I plan to remove the frozen_modules building part from Makefile, but there’re lots of places of frozen_modules or freeze. Is there a minimum effort for me to comment out something in Makefile to make it compile? Thank you!

There’s a comment in the file that builds frozen modules about how you can comment out a specific part of the file.
