Previously the compiler's default C++ standard was used unlike C where bsd.sys.mk explicitly sets a default language version. Setting an explicit default version will give a more uniform experience across different compilers and compiler versions. gnu++17 was chosen to match the default C standard. It is well supported by a wide range of clang (5+) and GCC (9+) versions. gnu++17 is also the default C++ standard in recent versions of clang (16+) and GCC (11+). As a result, many of the explicit CXXSTD settings in Makefiles had the effect of lowering the C++ standard instead of raising it as was originally intended and are removed. Note that the remaining explicit CXXSTD settings for atf and liblutok explicitly lower the standard to C++11 due to use of the deprecated auto_ptr<> template which is removed in later versions.
