perf tools: Allow building for ARM
Add definitions of rmb() and cpu_relax() and include the ARM
unistd.h header. The __kuser_memory_barrier helper in the helper
page is used to provide the correct memory barrier depending on
the CPU type.
[ The rmb() will work on v6 and v7, segfault on v5. Dynamic
detection to add v5 support will be added later. ]
