libstdc++: Fix x86 thread-safe one-time-construction implementation.

The root of the problem is that the existing implementation is based on the
ARM C++ ABI, which mandates a different guard variable layout than the
Itanium/x86 C++ one.

This patch modifies the implementation in a way that satisfies both ABIs (and
doesn't require changing the toolchains).
