This helps move perf.data files around. Signed-off-by: Charlie Jenkins --- Arnaldo mentioned that it would be useful to have syscalls all compile together for testing purposes and to allow perf.data info to be moved around with syscall info [1]. I am less familiar with perf trace so this is an RFC.
