The issue Blender hits is:

/builddir/build/BUILD/blender-2.80/source/blender/python/generic/py_capi_utils.c:722:30:
erro
r: dereferencing pointer to incomplete type 'PyInterpreterState' {aka 'struct
_is'}
  722 |   PyDict_SetItemString(interp->modules, "__main__", mod_main);
      |                              ^~
make[2]: ***
[source/blender/python/generic/CMakeFiles/bf_python_ext.dir/build.make:131:
sour

This is one of several other attempts to access "interp->modules". The
interpreter state is private API, and from Python 3.8 it is an opaque struct.
I haven't followed the interp changes closely enough, and I'm not familiar with
this part of CPython.
Victor, you might know: what's the best way to get "sys.modules" from C code?
(If you don't know off the top of your head, I can search further.)

"interp->modules" should be replaced by the public API function
PyImport_GetModuleDict.

Can someone create a patch on the issue ready to submit for upstream? Thanks.

Closing this report as the fix made Blender built with Python 3.8 and ported on
other release.
