Cross compiling wheel for armv5te

[lscorcia]

Hi, I'm trying to cross compile a wheel for package uv using maturin. I'm on an Ubuntu machine and I'm trying to build for the armv5te architecture. uv contains a rust module that I have been able to cross compile successfully using:

CARGO_TARGET_ARMV5TE_UNKNOWN_LINUX_GNUEABI_LINKER="/usr/bin/arm-linux-gnueabi-gcc" cargo build --release --target armv5te-unknown-linux-gnueabi

However, when running maturin I do get the wrong architecture out:

CARGO_TARGET_ARMV5TE_UNKNOWN_LINUX_GNUEABI_LINKER="/usr/bin/arm-linux-gnueabi-gcc" maturin build --release --target armv5te-unknown-linux-gnueabi --compatibility linux

Completes successfully, but builds the following:

uv-0.5.11-py3-none-linux_armv7l.whl

Installing this wheel on the machine reports this error:

ERROR: uv-0.5.11-py3-none-linux_armv7l.whl is not a supported wheel on this platform.

No additional info, but wheels built on the machine itself usually end with _armv5tel.whl.
Am I missing some other flag or parameter?

Add support for armv5te in #2409, can you confirm some information on the machine?
