Do I understand correctly that the `convertible-to` tests fail only in the combination of libc++/C++03/glibc?

It seems to me like the cure may be worse than the disease in this case, I'm not certain this is worth addressing given the complexity it introduces. In a certain way, this can be seen as a bug in glibc since there's no such issue in other standard modes and in other standard libraries.

Instead, we could add the missing test coverage and disable it with a comment based on `TEST_STD_VER <= 03`
