Regression: Can no longer build libsqlite3-sys

Hey there,

After updating the layer to the feature/rust-1.85.0 branch coming from 1.82.0, I noticed I couldn't build one of my projects' dependency crate libsqlite3-sys.

The full output is below:

error: failed to run custom build command for `libsqlite3-sys v0.30.1`

My target is aarch64-unknown-linux-gnu but for some reason TARGET is set to Some(x86_64-unknown-linux-gnu), which is my host system.
The -m64 option should only be enabled for x86-64, aix or powerpc64, see: https://github.com/rust-lang/cc-rs/blob/8ea5e95c10d0a6b169233736e681be5442af9671/src/lib.rs#L2149

When looking at the commits between 1.82.0 and 1.85.0 I saw this commit: https://github.com/rust-embedded/meta-rust-bin/commit/96c802da6a582978721e60b96487d460c8eadf38. After reverting this commit I was able to build successfully on 1.85.0.

To reproduce:

• Create Rust project with sqlx crate and the sqlite feature.
• Create a recipe which inherits cargo_bin from the current master branch.
• Build for aarch64-unknown-linux with a x86-64-unknown-linux host system.

Start with the cargo_bin inheritance and compare the changes from 1.82.0 to 1.85.0, especially commit 96c802da6a582978721e60b96487d460c8eadf38. Reproduce the sqlx SQLite build for an aarch64 target on an x86-64 host, then inspect the target values passed to cc-rs and confirm the build succeeds without the invalid compiler option.
