supertuxkart @1.2: undefined symbols "_glBlendEquationiARB", "_glBlendFunciARB" on 10.7

Description

​Build fails on 10.7: 

Undefined symbols for architecture x86_64:
  "_glBlendEquationiARB", referenced from:
      irr::video::COpenGLDriver::setRenderTarget(irr::core::array<irr::video::IRenderTarget, irr::core::irrAllocator<irr::video::IRenderTarget> > const&, bool, bool, irr::video::SColor) in libstkirrlicht.a(COpenGLDriver.cpp.o)
  "_glBlendFunciARB", referenced from:
      irr::video::COpenGLDriver::setRenderTarget(irr::core::array<irr::video::IRenderTarget, irr::core::irrAllocator<irr::video::IRenderTarget> > const&, bool, bool, irr::video::SColor) in libstkirrlicht.a(COpenGLDriver.cpp.o)

I'm not sure why this error happens: any glBlendFunciARB()/glBlendEquationiARB() usage is ​guarded by #elif defined(GL_ARB_draw_buffers_blend), which is ​defined in 10.9 SDK, but not 10.8 or earlier (I'm not sure why the 10.8 build succeeds); see "ARB_draw_buffers_blend" extension in ​macOS OpenGL capabilities tables. Whether this functionality is available at runtime is probably also dependent on what GPU is present.

(I personally do not use this port.)
