Yes, using that env var works. I'll dig deeper regarding
3rdparty/cpufeatures/cpu-features.c.

My python code removes barrel distortion from a webcam using
cv2.initUndistortRectifyMap and cv2.remap, and it now works well on the
RockPro64. I previously did the checker board calibration for the webcam,
per opencv website, and the same coefficients work.

I have a new purpose for my new ARM64 toy :)

Thank you all for the help!
