it's time to change the C++ default to gnu++17. I've committed the patch after
testing x86_64-pc-linux-gnu and powerpc64le-unknown-linux-gnu. Brace

Just a small note that 510.parest_r SPEC 2017 benchmark can't be built now
with default changed to -std=c++17. The spec config needs to be adjusted.

<!> Error during startup: Register_Function() or cMathFunction: attempt to register
function "SPEC_HYPOT" with wrong number of arguments 2, should be 3.
which is about call of std::__hypot3 which has newly 3 args since c++ 17:
