Just as on aarch64, x86's wider long double experiences loss of
precision with from_chars implemented in terms of double. Expect the
execution fail.
Bootstrapped on x86_64-linux-gnu. Also tested on ppc- and x86-vx7r2
with gcc-12.
for libstdc++-v3/ChangeLog
* testsuite/20_util/to_chars/long_double.cc: Expect execution
fail on x86-vxworks.
