 That's because linux doesn't use collect2.  With 3.1, I currentls see
 
 bash-2.05a$ nm libstdc++.sl.4.0|grep GLOBAL|grep FI|less
 _GLOBAL__FI_libgcc_s_sl|        -4|uext  |stub   |
 _GLOBAL__FI_libgcc_s_sl|          |undef |code   |
 _GLOBAL__FI_libstdc___sl_4_0|    484704|extern|entry  |
 _GLOBAL__FI_libstdc___sl_4_0|    484728|extern|code   |$CODE$
 _GLOBAL__FI_libstdc___sl_4_0|    485100|uext  |stub   |
 
 The library internal name is
 
 bash-2.05a$ chatr libstdc++.sl.4.0
 libstdc++.sl.4.0:
 ...
          internal name:
 	      libstdc++.sl.4
 
 This is ok.  However, the issue reported must be kept in mind when the
 library version is next updated.
