+Subject: [PATCH 2/2] Reuse -fdebug-prefix-map to replace -ffile-prefix-map
+
+The oe-core may use external toolchain to compile,
+which may not support -ffile-prefix-map.
+
+Since we use -fdebug-prefix-map to do the same thing,
+so we could reuse it to replace -ffile-prefix-map.
+
+Upstream-Status: Inappropriate[oe-core specific]
