spa: switch the include header test to C++ by default

Browse source 
If we have a C++ compiler, compile all the #include tests with that - it'll
pick up any issues that a C compiler will pick up anyway. This saves us from
having a separate C++ compiler test and it'll test each header separately for
C++ compatibility..
