You don't fully explain your reasoning.  However, this change seems a bit
pessimistic.  If you want to test implicit instantiation, why not just do
it on systems with weak linking semantics and provide the explicit needed
when this isn't available?  We already have _GLIBCPP_SUPPORTS_WEAK in
config.h, so this is trivial to implement.
