board.h missing extern C guard

[aberger]

This is a bug report. I am using SDK_2.16.000 for the MCXA153. When I use the "Create a new C/C++ project" wizard in MCUXpresso and create a new C++ project, the generated code fails to build because of 

undefined reference to `BOARD_InitDebugConsole()'

This is because board.h is missing the extern C guard, which can be fixed as follows:

#ifdef __cplusplus
extern "C" {
#endif

void BOARD_InitDebugConsole(void);

#ifdef __cplusplus
}
#endif
