+Subject: [PATCH] build: Remove `--test-wasm-stdlib` option
+
+We already adopted wasi-libc 27, which includes the necessary fix for
+null builds, so we no longer need a way to run wasm tests without
+building. Also removing the logic that unintentionally enforced
+`--test-wasm-stdlib` whenever `--build-wasm-stdlib` was specified.
