catalyst: fix build on x86_64-darwin

[qbisi]

darwin stdenv swtich to use system libc++ from sdk, hence the abi test failed on x86_64-darwin.
fix build by disabling abi test on x86_64-darwin.

• Built on platform:
  • x86_64-linux
  • aarch64-linux
  • x86_64-darwin
  • aarch64-darwin
• Tested, as applicable:
  • NixOS tests in nixos/tests.
  • Package tests at passthru.tests.
  • Tests in lib/tests or pkgs/test for functions and "core" functionality.
• Ran nixpkgs-review on this PR. See nixpkgs-review usage.
• Tested basic functionality of all binary files, usually in ./result/bin/.
• Nixpkgs Release Notes
  • Package update: when the change is major or breaking.
• NixOS Release Notes
  • Module addition: when adding a new NixOS module.

@NixOS/darwin-core is there anything changed to darwin stdenv in #444862

[reckenrode]

Clang was updated to Clang 21. The SDK stuff is coming in the next cycle.

[qbisi]

I can disable the failing test, just curious about the root cause of the abi test failing. (who bring in those unexpected symbols)
Note that catalyst is not broken on aarch64-darwin.

That might also have been the staging cycle when Darwin switched to the system libc++.

Probably the only way to know is to build locally with --keep-failed to check the log for which symbols it’s unexpectedly finding.

[qbisi]

According to build log, these symbols are unwanted.

I guess these symbols come from libc++ from the latest SDK.
