Auto merge of #106646 - Amanieu:ilp32-object, r=Mark-Simulacrum

Fix aarch64-unknown-linux-gnu_ilp32 target

This was broken because the synthetic object files produced by rustc were for 64-bit AArch64, which caused link failures when combined with 32-bit ILP32 object files.

This PR updates the object crate to 0.30.1 which adds support for generating ILP32 AArch64 object files.
