[libstdc++] [testsuite] xfail double-prec from_chars for 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 aarch64-*-vxworks.
for libstdc++-v3/ChangeLog
* testsuite/20_util/from_chars/4.cc: Skip long double test06
on aarch64-vxworks.
* testsuite/20_util/to_chars/long_double.cc: Xfail run on
aarch64-vxworks.
