Is there a required condition?\n\nAlways.\n\n### What is the expected behavior? Why is that the expected behavior?\n\nAll tests should pass. If some dependency (test or otherwise) needs to be built for a test, the build system should take care of it automatically.\n\n### What do you see instead?\n\n```\nnot ok 2796 parallel/test-permission-drop-ffi\n  ---\n  duration_ms: 55.72600\n  severity: fail\n  exitcode: 1\n  stack: |-\n    /tmp/guix-build-node-26.8.2.drv-0/node-v26.8.2/test/ffi/ffi-test-common.js:21\n        throw new Error(\n        ^\n    \n    Error: Missing FFI test fixture library: /tmp/guix-build-node-26.8.2.drv-0/node-v26.8.2/test/ffi/fixture_library/build/Release/ffi_test_library.so.
