+Subject: [PATCH] va: Fix -Wl,--version-script check with LLD 17
+
+LLD 17 uses --no-undefined-version by default, so the check currently
+fails due to vaCreateSurface being undefined. This commit replaces that
+check with a generic check in the top level meson.build, using the
+conftest.syms file.
