+Subject: [PATCH] tests/vpci: drop explicit -g use
+
+The explicit use of -g is embedded debug information and paths
+into the output files, which breaks QA. Investigating how to
+mitigate this via prefix maps is a future TODO item. For now,
+we just stop using -g
+
+Upstream-Status: Inappropriate [oe specific]
