[BUILD] Build will fail on some 32-bit platforms, since configure does not check for a need for libatomic linking

[barracuda156]

Environment

Operating System: macOS 10.6 / ppc
Version / Commit SHA: 11.0.0
Other: gcc 13.2.0

Describe the bug

Linking fails due to missing -latomic.
libatomic is not invoked because configure does not check for such a need.

To Reproduce

Steps to reproduce the behavior:
Build on a platform which needs libatomic for 8-byte atomics.

Expected behavior

CMake should check for hardware support for 8-byte atomics, and if that is not detected, pass -latomic flag.
