The last time I tried building rust (1.83) on macOS a couple weeks ago, I saw

  = note: ld: warning: ignoring duplicate libraries: '-lm'
          ld: warning: object file (/Users/test/pkgsrc/lang/rust/work/rustc-1.83.0-src/build/aarch64-apple-darwin/stage0-rustc/aarch64-apple-darwin/release/deps/librustc_codegen_llvm-439f221997fe20a7.rlib[19](7372e21ddc8be4fd-PassWrapper.o)) was built for newer 'macOS' version (15.2) than being linked (11.0)

          Undefined symbols for architecture arm64:

                llvm::sys::fs::copy_file(llvm::Twine const&, llvm::Twine const&) in librustc_llvm-9d488e0d9689de6a.rlib[2159](Path.cpp.o)
          ld: symbol(s) not found for architecture arm64
          clang: error: linker command failed with exit code 1 (use -v to see invocation)


so I think that's not a regression.

Does lang/rust (1.83) build for you in the same environment?
