Fails to build with GCC 12 (pre-release) on ppc64le #21465
Description
System information (version)
- OpenCV => 4.5.5
- Operating System / Platform => Fedora Linux Rawhide (development version),
ppc64le(64-bit PowerPC, little-endian) - Compiler => GCC 12.0.0 (pre-release)
Detailed description
GCC was just updated to a pre-release of 12.0.0 in Fedora Rawhide (the development version of Fedora Linux), and OpenCV and packages that use it are failing to compile on ppc64le due to a problem with AltiVec/VSX intrinsics.
The downstream bug report is here.
I don’t know if this is an OpenCV bug or a GCC 12 bug.

Steps to reproduce
Compile with GCC 12 on ppc64le.
Issue submission checklist
- I report the issue, it's not a question
- I checked the problem with documentation, FAQ, open issues,
forum.opencv.org, Stack Overflow, etc and have not found solution - I updated to latest OpenCV version and the issue is still there
- There is reproducer code and related data files: videos, images, onnx, etc N/A
