[libstdc++] [testsuite] xfail double-prec from_chars for x86_64 ldbl
When long double is wider than double, but from_chars is implemented
in terms of double, tests that involve the full precision of long
double are expected to fail. Mark them as such on x86_64-*-vxworks*.
for libstdc++-v3/ChangeLog
* testsuite/20_util/from_chars/4.cc: Skip long double test06
on x86_64-vxworks.
* testsuite/20_util/to_chars/long_double.cc: Xfail run on
x86_64-vxworks.
(cherry picked from commit 282e4e745981c5c6e3edaae315e1f499a45402df)
