Cannot build bare metal mach-o binaries

I tried to compile a bare metal aarch64 Rust Mach-O binary with the following target json spec:

{
  "abi": "softfloat",
  "arch": "aarch64",
  "crt-objects-fallback": "false",
  "data-layout": "e-m:o-i64:64-i128:128-n32:64-S128-Fn32",
  "disable-redzone": true,
  "features": "+v8a,+strict-align,-neon,-fp-armv8",
  "is-builtin": false,
  "linker": "ld64.lld",
  "linker-flavor": "gnu-lld",
  "llvm-target": "aarch64-unknown-none-macho",
  "max-atomic-width": 128,
  "metadata": {
    "description": "Bare ARM64, softfloat",
    "host_tools": false,
    "std": false,
    "tier": 2
  },
  "panic-strategy": "abort",
  "relocation-model": "static",
  "stack-probes": {
    "kind": "inline"
  },
  "target-pointer-width": "64"
}

I expected to see this happen: No errors

Instead, this happened:

rustc-LLVM ERROR: Global variable '__rustc_debug_gdb_scripts_section__' has an invalid section specifier '.debug_gdb_scripts': mach-o section specifier requires a segment and section separated by a comma.

rustc --version --verbose:

rustc 1.83.0-nightly (6f4ae0f34 2024-10-08)
binary: rustc

Unfortunately RUST_BACKTRACE=1 doesn't change anything so I cannot give backtrace at the moment. I will look into building rustc if needed.

Start by reproducing the failure with the aarch64 bare-metal target JSON from the issue and inspect how rustc emits the rustc_debug_gdb_scripts_section section for Mach-O targets. Done means the target builds without LLVM rejecting the .debug_gdb_scripts section specifier; no project files or tests are named in the report.
