I don't see why debug and special sections shouldn't be kept when
they are part of a group:

diff --git a/bfd/elflink.c b/bfd/elflink.c

       for (isec = ibfd->sections; isec != NULL; isec = isec->next)
-  if (elf_next_in_group (isec) == NULL
-      && ((isec->flags & SEC_DEBUGGING) != 0

     isec->gc_mark = 1;
     }
   return TRUE;
