scons: Resolve backtrace implementation existence testing failure
Change backtrace implementation testing code not to have NULL pointer. SCons fails to find backtrace implementation even if it exists. The implementation testing code contains NULL pointers as a backtrace buffer argument. Some compilers check the buffer is NULL pointed or not, and generate a compilation error.
