package/supertux: remove libglu dependency
"The inclusion of GLU is historical. [...] It's not needed for GLEW to build or run, but it's opt-out that reason. I'd recommend using -DGLEW_NO_GLU since GLU is rarely seen in modern codebases nowadays." https://github.com/nigels-com/glew/issues/192#issuecomment-411641657 Each package using glew.h has to decide whether to use the opt-out for glu or not. Since supertux does not need libglu we can safely remove the dependency by adding -DGLEW_NO_GLU to TARGET_CXXFLAGS. Signed-off-by: Bernd Kuhls <bernd.kuhls@t-online.de> Signed-off-by: Yann E.
