It strictly IS about C++11 support, because *that support defines the
runtime ABI*. You have no options; if you insist on the system provided
runtime, then either it provides the C++11 ABI or it does not, and that
defines what level of C++ support you provide.

That is precisely why this problem exists, and why it will continue to
exist unless we provide viable support for other than the system's C++
runtime.
