[Pkg-rust-maintainers] Bug#1124553: librust-pyo3-ffi-dev: cannot be installed for foreign architectures

[Helmut Grohne]

Package: librust-pyo3-ffi-dev
Version: 0.27.2-1
Tags: patch
User: debian-cross at lists.debian.org
Usertags: cross-satisfiability
Control: affects -1 + src:blake3-py src:breezy src:dulwich src:lintian-brush src:pendulum src:pydantic-core src:pysequoia src:python-bcrypt src:python-cotengrust src:python-cramjam src:python-cryptography src:python-fastbencode src:python-jellyfish src:python-libcst src:python-minijinja src:python-nh3 src:python-orjson src:python-proton-vpn-local-agent src:python-pycddl src:python-upstream-ontologist src:python-watchfiles src:python-zxcvbn-rs-py src:rpds-py src:ruff src:rust-buildlog-consultant src:rust-ognibuild src:safetensors src:silver-platter src:tiktoken src:unicode-segmentation-rs

The affected packages cannot be cross built from source, because they
transitively depend on the host architecture librust-pyo3-ffi-dev and
that package cannot be installed for foreign architectures, because it
depends on python3-all-dev. As far as I understand it, the crate is used
for building Python extension modules. For that purpose, the dependency
should be python3-all-dev:any plus libpython3-all-dev. I'm attaching a
patch for your convenience.
