Bug#908685: sdl-ball FTCBFS: uses CC to store a C++ compiler

[Helmut Grohne]

Source: sdl-ball
Version: 1.02-2
Tags: patch upstream
User: helmutg at debian.org

sdl-ball fails to cross build from source, because the upstream Makefile
uses CC to store a C++ compiler. dh_auto_build substitutes a C compiler
and that fails. After making it use CXX, sdl-ball cross builds
successfully. Please consider applying the attached patch.
