With the perf trace command you can specify system calls with wildcards. To support this on s390, a system call table must be provided to perf. Provide a script to create the perf system call table based on the defines in arch/s390/include/uapi/asm/unistd.h (copied to tools/arch/s390/...). Note that the first patch can be applied independent of the second and third patch. In case they need further discussion, please consider to integrate the first one. The second and third patches complete the work to remove the audit library dependency for perf trace when an architecture supports system call tables. Inspired by the generation of the system call tables, create a similar approach to generate errno name mappings. Introduce the errno_to_name() function to replace audit_errno_to_name() in perf trace. The third patch changes the build process to build and run perf trace without requiring the audit library anymore (for those architectures that have system call table support). Note: The patch set is based on the linux master branch (968edbd93c0cbb).
