Tools/freeze/freeze.py doesn't support config directory using multiarch nor directory using a sys.platlibdir different than "lib". In short, it doesn't work on Fedora 33 which uses:

/usr/lib64/python3.10/config-3.10-x86_64-linux-gnu/

It might be possible to copy/paste the code creating the config-xxx path from Lib/sysconfig.py to Tools/freeze/freeze.py, but I would prefer to reuse code if possible, to make the code more sustainable.

Maybe we can add a private function to get the path to the "config" directory.

Or even a public function.

Tools/freeze/freeze.py is broken for 4 years, since Python 3.6 which added sys.implementation._multiarch to the config directory in sysconfig:

    - Issue #23968: Rename the platform directory from plat-$(MACHDEP) to
      plat-$(PLATFORM_TRIPLET).
      Rename the config directory (LIBPL) from config-$(LDVERSION) to
      config-$(LDVERSION)-$(PLATFORM_TRIPLET).
      Install the platform specifc _sysconfigdata module into the platform
      directory and rename it to include the ABIFLAGS.

I found this issue while working on bpo-42591 which exported the missing Py_FrozenMain() symbol.

There are better maintained alternatives:

* PyOxidizer
* pyInstaller
* bbFreeze
* py2exe
* cx_Freeze
* py2app
* etc.

bpo-42613: Fix freeze.py config directory (GH-23792)
https://github.com/python/cpython/commit/1c653f17cb84d81df3a74ab0b42140d2bb68c5c4

I tested my fix with these commands:
---
./configure --with-platlibdir=lib64 --enable-shared --prefix /opt/py310 CFLAGS="-O0"
make
make install
# move outside CPython source tree
cd

mkdir hello
cd hello
echo 'print("hello")' > hello.py

cp -R  ~/python/master/Tools/freeze/ .
LD_LIBRARY_PATH=/opt/py310/lib /opt/py310/bin/python3.10 freeze/freeze.py hello.py
---

Output:
---
$ LD_LIBRARY_PATH=/opt/py310/lib ./hello 
hello
