imx8dx libsdl2 bug issue

1.在L5.4.70 BSP上，默认编译的libsdl2会显示颜色错误，L5.10.x这个版本也存在同样的问题。至少需要libsdl2-2.0.16版本及以上，才能使用颜色正常。

2.在使用libsdl2-2.0.16版本后，默认会使用opengl进行渲染，但未指定opengl版本（不知道这是为什么），在代码执行到SDL_RenderPresent(renderer); 会报出段错误in glOrtho () from /usr/lib/libGL.so.1。此时在libsdl2编译配置中禁用opengl、opengl es1,再次编译，会默认使用opengl es2,此时可以正常运行。（没有尝试只禁用opengl）

Hi @songhongliang

I hope you are doing well.

IMX8 is not supporting libsdl2, It does support libsdl up to version 1.2.

Thanks & Regards
