    libstdc++: Fix build for targets without _Float128 [PR109921]

    My r14-1431-g7037e7b6e4ac41 change caused the _Float128 overload to be
    compiled unconditionally, by moving the USE_STRTOF128_FOR_FROM_CHARS
    check into the function body. That function should still only be
    compiled if the target actually supports _Float128.

    libstdc++-v3/ChangeLog:

            PR libstdc++/109921
            * src/c++17/floating_from_chars.cc: Check __FLT128_MANT_DIG__ is
            defined before trying to use _Float128.
