+Subject: [PATCH] Drop ar 'u' argument
+
+binutils/ar is configured in deterministic mode by default making the
+'u' argument irrelevant while leading to warning massages similar to:
+
+| ar: `u' modifier ignored since `D' is the default (see `U')
+
+We also add 'D' flag explicitely to not rely in the default configuration
+for reproducible archives.
+
+Upstream-Status: Inappropriate [OE specific]
