ELF: visibility handling |

Message

  The ELF spec mandates certain behavior there which we don't properly
follow. In fact some non-conforming testcases exit, which therefore
are in need of adjustment.

1: gas/ELF: restrict visibility changes
2: gas/ELF: warn upon non-default visibility of local symbols
3: objcopy: zap ELF visibility when localizing symbols
