libstdc++: Check FE_TONEAREST is defined before using it
We need to test that FE_TONEAREST is defined before we may use it along
with fegetround/fesetround to adjust the floating-point rounding mode.
This fixes a build failure with older versions of newlib.
libstdc++-v3/ChangeLog:
* src/c++17/floating_from_chars.cc (from_chars_impl)
[!defined(FE_TONEAREST)]: Don't adjust the rounding mode.
* src/c++17/floating_to_chars.cc (__floating_to_chars_precision):
Likewise.
