+Subject: [PATCH] build: Fix version script linker support detection
+
+When the linker uses --no-undefined-version either specified by the user
+or as the default behavior (such as with newer clang >= 16 releases), a missing symbol definition will cause a linker error if that symbol is
+listed in the version script.
+
