Patch to make printf/printk work for MBX8xx

Hi,

I have started using C++ with rtems (m68k). I'm not sure but I think that
there is no make-cxx-exe available for the m68k bsp.
I could link my application by just adding stdc++ to LD_LIBS. Is this
equivalent or does the make-cxx-exe script more.

Peter
