For the code without <rte_cycles.h> could run on x86, I think I have found the reason. Through the path <rte_memory.h> -> <rte_eal_memconfig.h> -> <rte_spinlock.h>, the <rte_spinlock.h> is included. <rte_spinlock.h> is independent on each architecture. And on x86 the <rte_spinlock.h> includes its own "rte_cycles.h", while other architectures do not.
