    libstdc++: Fix endianness issue with IBM long double [PR98384]

    The code in std::to_chars for extracting the high- and low-order parts
    of an IBM long double value does the right thing on powerpc64le, but not
    on powerpc64be.  This patch makes the extraction endian-agnostic, which
    fixes the execution FAIL of to_chars/long_double.cc on powerpc64be.

    libstdc++-v3/ChangeLog:

            PR libstdc++/98384
            * src/c++17/floating_to_chars.cc (get_ieee_repr): Extract
            the high- and low-order parts from an IBM long double value
            in an endian-agnostic way.=
