When compiling latest Saturn Next I get a bunch of warnings about certain warning flags not being in C++

For some reason the Makefile tries to pass the warning flags to g++ even if they aren't available.

well currently all build flags gets passed to both c and c++ compiler, this does not do any harm and was mostly done for simplicity sake (didnt want to introduce any weird bugs when splitting things up)
but it is planned to fix this in the future
