Rollup merge of #117259 - dtolnay:macho, r=Nilstrieb

Declare rustc_target's dependency on object/macho

Without this, `cargo check` fails in crates that depend on rustc_target.

`rustc_target` unconditionally contains its `spec` module (i.e. there is no `#[cfg]` on the `mod spec;`). The `spec/mod.rs` also does not start with `#![cfg]`.

aa91057796/compiler/rustc_target/src/lib.rs (L37)

Similarly, the `spec` module unconditionally contains `apple_base`.

aa91057796/compiler/rustc_target/src/spec/mod.rs (L62)

And, `apple_base` unconditionally refers to `object::macho`.

aa91057796/compiler/rustc_target/src/spec/apple_base.rs (L176)

So I figure there is no way `object::macho` isn't needed by rustc.

`object::macho` only exists if the `object` crate's "macho" feature is enabled. https://github.com/gimli-rs/object/blob/0.32.0/src/lib.rs#L111-L112
