Anyway,
EDM, Shaper, or a small drilled hole in the corner and cleaned out with an end mill. Granted it won't be a sharp inside corner, but the radius will be as small as the drill you use.

A rotary broaching tool holder should fit on your CNC machine. To make the square hole using this tool, first pre-drill a hole to the flat-to-flat dimension, then use a broach of the same dimension to take out the square corners. The best way to understand how this works is to watch the video.
