perf util: Introduce architecture specific errno/name mapping Introduce a script that generates a mapping of errno numbers to their names for each architecture that is supported by perf (i.e. has a subdirectory in tools/perf/arch/). The errno mapping is generated as part of the trace beautifiers and can be used by including the trace/beauty/arch_errno_names.c file. Then, use arch_syscalls__strerrno() to look up an errno value to obtain the errno name (e.g. ENOENT) for a particular architecture.
