I've taken the liberty of filing this upstream as a GCC/libstdc++ issue.
The extremely condensed version of the issue is that libstdc++ builds by
selecting config/os/newlib, but it does not pick --enable-clocale=newlib.
Enabling the more global --with-newlib flag would do the latter for us,
but it might have other, less desirable effects on top of that.
