             this point we have not seen all the input files, so it is
             possible that DEF_REGULAR is not set now but will be set
             later (it is never cleared).  In case of a weak definition,
             DEF_REGULAR may be cleared later by a strong definition in
             a shared library.  We account for that possibility below by
             storing information in the relocs_copied field of the hash
             table entry.  A similar situation occurs when creating
             shared libraries and symbol visibility changes render the
             symbol local.

             If on the other hand, we are creating an executable, we
             may need to keep relocations for symbols satisfied by a
             dynamic library if we manage to avoid copy relocs for the
             symbol.  */
