libstdc++: Disable std::format of _Float128 if std::to_chars is innaccurate This restricts std::format support for _Float128 (and __float128) to targets where glibc provides __strfromf128 and so can give correct output. libstdc++-v3/ChangeLog: * include/std/format [__FLT128_DIG__] (_GLIBCXX_FORMAT_F128): Only support formatting _Float128 when glibc provides the functionality needed for accurate std::to_chars.
