Hello, Please find my patch attached for review.
Summary of Changes: - GCC 15 defaults to `-std=gnu23`, causing build failures in `testsuite` due to outdated C function declarations. This patch updates the function declarations to align with modern standards. - Introduced `cpu_relax.h` to support `cancel3` and `cancel5` tests by providing architecture-specific instructions. Thanks & regards Thirumalai Nagalingam
