Ubuntu aarch64/arm7 fail to import sync::GILProtected

[nrposner]

Bug Description

Similar to #2385, maturin fails automated checks for some Ubuntu platforms , linux (ubuntu-22.04, aarch64), musllinux (ubuntu-22.04, arm7), due to unresolved import of pyo3::sync::GILProtected.

   Compiling numpy v0.23.0
error[E0432]: unresolved import `pyo3::sync::GILProtected`
  --> /root/.cargo/registry/src/index.crates.io-6f17d22bba15001f/numpy-0.23.0/src/datetime.rs:63:12
   |
63 | use pyo3::{sync::GILProtected, Bound, Py, Python};
   |            ^^^^^^^^^^^^^^^^^^ no `GILProtected` in `sync`
   |

As yet unable to locally replicate error with Docker. Local machine is a Mac, for which all automated tests pass without error.

Failed runs with detailed errors linked above.

Your maturin version (maturin --version)

1.8.1

Your Python version (python -V)

3.13.1

Your pip version (pip -V)

24.3.1

What bindings you're using

pyo3

Does cargo build work?

• Yes, it works

If on windows, have you checked that you aren't accidentally using unix path (those with the forward slash /)?

• Yes

Steps to Reproduce

1. Import both pyo3 = 0.23.3 and numpy = 0.23.0
2. Create a pyfunction that forces the numpy dependency to compile (does not actually have to use numpy in any capacity).
3. Add this pyfunction to a pymodule.
4. Push to github. Automated checks for certain ubuntu versions will fail to import pyo3::sync::GILProtected. See runs linked above for full errors. The minimal repo that replicates this bug is located at https://github.com/nrposner/pyo3_bug
