This proc should use -std=gnu++29 but I forgot to update it in
r17-1905-g70e630b6d29b75 so it's now out of date. Replace the hardcoded
option by reusing the existing $v3_max_std variable defined earlier.
libstdc++-v3/ChangeLog:
* testsuite/lib/libstdc++.exp (check_v3_target_cpp_feature_test):
Use $v3_max_std variable instead of hardcoding the latest -std
option.
