+    elf: Copy l_addr/l_ld when adding ld.so to a new namespace
+    
+    When add ld.so to a new namespace, we don't actually load ld.so.  We
+    create a new link map and refers the real one for almost everything.
+    Copy l_addr and l_ld from the real ld.so link map to avoid GDB warning:
+    
+    warning: .dynamic section for ".../elf/ld-linux-x86-64.so.2" is not at the expected address (wrong library or version mismatch?)
+    
+    when handling shared library loaded by dlmopen.
