cpp_link_stdlib/cpp_set_stdlib examples

Resolves #179

Hm I'm realizing now these have shared_flag, but how come? I think this as-is will fail at runtime because this doesn't support creating libfoo.so afaik.

[opilar]

Why? Static library doesn't link. Or you talk about different header files?

[alexcrichton]

Oh well so this option is intended for the C++ standard a piece of code is compiled with, but cpp_set_stdlib and such aren't really relevant for linkage other than telling rustc it may want a different C++ standard library.

Perhaps the shared_flag could be removed and libfoo.so could be changed to libfoo.a?

[opilar]

Oh year. You're right! It's not only about linking.

@opilar are you still working on changing this?

I would expect the example for cpp_link_stdlib to call cpp_link_stdlib, not cpp_set_stdlib.

[opilar]

Thank you! My bad.

@alexcrichton @dtolnay thank you for your help.
