same output with all binutils versions mentioned above, but:

$ objdump -t .libs/io-inst.o | grep _ZNSdC2Ev
00000000 l    d  .gnu.linkonce.t._ZNSdC2Ev      00000000 
00000000  w    F .gnu.linkonce.t._ZNSdC2Ev      00000045 _ZNSdC2Ev

$ objdump -t .libs/libstdc++.so | grep _ZNSdC2Ev
00056730 l     F .text  00000045              _ZNSdC2Ev

$ objdump -t .libs/libstdc++.a | grep _ZNSdC2Ev
00000000 l    d  .gnu.linkonce.t._ZNSdC2Ev      00000000 
00000000  w    F .gnu.linkonce.t._ZNSdC2Ev      00000045 _ZNSdC2Ev
