This is a libstdc++ bug, caused by the libstdc++ directory reorganization and
introduction of the convenience libraries.
The various source files in libstdc++ that use .symver directives were written
with the assumption that libtool builds things twice, once without -DPIC for
libstdc++.a and once with -DPIC for libstdc++.so.6.
The compatibility stuff with symbol versions only belongs to libstdc++.so.6
obviously, otherwise you get the errors you are getting and gold is broken if
it doesn't error out on that.
Unfortunately the convenience libraries contain solely -DPIC code (-fPIC isn't
a big deal, but -DPIC is here), so everything is compiled just once and
libstdc++.a (incorrectly) as well as libstdc++.so.6 (correctly) is built with
the .symver stuff in the objects.
