Not an expert, but I when I had to do something like that I followed
this guide:

Yep, this is exactly the kind of tool I meant when I complained about relying on CPython built with nonfree MSVC compiler. If you dig into PyInstaller's source you'll most likely find out that it just fetches a prebuilt Python interpreter from somewhere. In case of Windows (including Wine) that interpreter will be one built with M$' C compiler unless you make your own effort to replace it with for example a GCC-built one.

The problem here is that even though we know GCC can build (a properly patched version of) CPython under Windows, we don't know if it can also do it under Wine. In the past I had an issue with libmariadb which I could not build under Wine because of some missing headers or APIs. Here we might (or might not!) hit the same issue :/
