-Wold-style-definition is not a supported option for C++ builds. To prevent it being passed: * the list of compiler flags to be excluded from C++ builds is moved to be toolchain-specific; * -Wold-style-definition is added to that list for gcc and clang; * -Wold-style-definition is moved from zephyr_compiler_options to zephyr_cc_option so the option checking code is executed for it.
