Comment:

 I've been working on that today while trying to fix #28238 and it's not
 that hard for x86_64 at least. I got everything cross-compiled for that
 architecture, just with a small patch needed for the Rust config.

 For i686 I got pretty far but am blocked right now by a PyCrypto/Wine
 issue:
