I am missing some instantiations, but that linker error is fixed by
this change:

--- a/libstdc++-v3/src/c++11/cow-string-inst.cc

Thie missing ones are due to the fact that insert/erase/replace etc.
take iterator arguments in C++03 and const_iterator in C++11, so the
explicit instantiations in src/c++11/string-inst.cc only generate the
const_iterator form.  I'm not sure whether to add explicit
instantiations for the other forms, or just say the arguments are
always const_iterator even in C++03 mode.
