Tiezhu Yang ece7f7c050 perf bench syscall: Add fork syscall benchmark ... This is a follow up patch for the execve bench which is actually fork + execve, it makes sense to add the fork syscall benchmark to compare the execve part precisely. Some archs have no __NR_fork definition which is used only as a check condition to call test_fork(), let us just define it as -1 to avoid build error.
