libstdc++: Remove duplicate definition of _Float128 std::from_chars [PR110077]
When long double uses IEEE binary128 representation we define the
_Float128 overload of std::from_chars inline in <charconv>. My changes
in r14-1431-g7037e7b6e4ac41 cause it to also be defined non-inline in
the library, leading to an abi-check failure for (at least) sparc and
aarch64.
Suppress the definition in the library if long double and _Float128 have
are both IEEE binary128.
libstdc++-v3/ChangeLog:
PR libstdc++/110077
* src/c++17/floating_from_chars.cc (from_chars) <_Float128>:
Only define if _Float128 and long double have different
representations.
