Pull more perf tools updates from Namhyung Kim:
 "These are remaining changes and fixes for this cycle.
  Build:
   - Allow generating vmlinux.h from BTF using `make GEN_VMLINUX_H=1`
     and skip if the vmlinux has no BTF.
   - Replace deprecated clang -target xxx option by --target=xxx.
  perf record:
   - Print event attributes with well known type and config symbols in
     the debug output like below:
       # perf record -e cycles,cpu-clock -C0 -vv true

   - Update AMD IBS event error message since it now support per-process
     profiling but no priviledge filters.
       $ sudo perf record -e ibs_op//k -C 0
       Error:
       AMD IBS doesn't support privilege filtering. Try again without
       the privilege modifiers (like 'k') at the end.

   - Support CSV style output using -x option

   - Add --output option to save the data to a file not to be interfered
     by other debug messages.
  Test:
   - Fix event parsing test on ARM where there's no raw PMU nor supports
     PERF_PMU_CAP_EXTENDED_HW_TYPE.
   - Update the lock contention test case for CSV output.
   - Fix a segfault in the daemon command test.
  Vendor events (JSON):
   - Add has_event() to check if the given event is available on system
     at runtime. On Intel machines, some transaction events may not be
     present when TSC extensions are disabled.
   - Update Intel event metrics.
  Misc:
   - Sort symbols by name using an external array of pointers instead of
     a rbtree node in the symbol. This will save 16-bytes or 24-bytes
     per symbol whether the sorting is actually requested or not.
   - Fix unwinding DWARF callstacks using libdw when --symfs option is
     used"
