This bug is appearing while linking opie libraries. I have a self contained 

The error message is

launcher.o: In function `Launcher::properties(AppLnk*)':
launcher.cpp:(.text+0x21c8): undefined reference to

the fist link generate a shared library which contains HIDDEN for visibility
for this symbol with out the fix for PR #9679 this works fine because visibility
is default.

The problem is happening after the fix for PR #9679 was committed.

   /* Skip weak definitions of symbols that are already defined.  */
   if (newdef && olddef && newweak)
-    *skip = TRUE;
+    {
+      *skip = TRUE;
+      /* Merge st_other.  If the symbol already has a dynamic index,
+        but visibility says it should not be visible, turn it into a
+        local symbol.  */
+      elf_merge_st_other (abfd, h, sym, newdef, newdyn);
+      if (h->dynindx != -1)
+       switch (ELF_ST_VISIBILITY (h->other))
+         {
+         case STV_INTERNAL:
+         case STV_HIDDEN:
+           (*bed->elf_backend_hide_symbol) (info, h, TRUE);
+           break;
+         }
+    }

is causing the link to fail.
