Bug report

Bug description:

When CPython is built withoutHAVE_DYNAMIC_LOADING set, we currently leave out a small handful of code in Python/import.c and Python/importdl.c. However, there is a bunch more that should probably be excluded (via#ifdef HAVE_DYNAMIC_LOADING):

• some functions and constants in Python/importdl.c and Include/internal/pycore_importdl.h
• some functions, constants, and state in Python/import.c and Include/internal/pycore_import.h
• some code in Lib/importlib/_bootstrap_external.py
• maybe some code in Objects/moduleobject.c
• builds for Modules/Setup.stdlib
• checks in Tools/build/check_extension_modules.py
• modules listed by Tools/build/generate_stdlib_module_names.py

(Also seegh-122907.)

Getting this all correct would probably take a fair amount of effort. Perhaps the big question is would it be worth addressing all these cases?
