+        powerpc: Optimized strncat for POWER7/PPC64
+    
+        With 3eb38795dbbbd816 (Simplify strncat) the generic algorithms uses
+        strlen, strnlen, and memcpy.  This is faster than POWER7 current
+        implementation, especially for unaligned strings (where POWER7 code
+        uses byte-byte operations).
+    
+        This patch removes the assembly implementation and uses a multiarch
+        specialization based on default algorithm calling optimized POWER7
+        symbols.
+
