The architectural specific headers perf_regs.h currently rely on the host architecture's 'asm/perf_regs.h'. This can lead to compilation inconsistencies or failures when including and building perf for a target architecture that differs from the host's architecture. Explicitly point to the UAPI headers within the tools source tree using relative paths. This ensures that perf is always built against the intended architecture. No functional changes are intended.
