Hendrik Brueckner 164a747f1a perf s390: Generate system call table from asm/unistd.h
This should speed up accessing new system calls introduced with
the kernel rather than waiting for libaudit updates to include
them.

Committer testing:

  $ rm -rf /tmp/build/perf
  $ mkdir /tmp/build/perf
  $ make srctree=/home/acme/git/perf -C tools/perf/arch/s390 OUTPUT=/tmp/build/perf/ archheaders
  make: Entering directory '/home/acme/git/perf/tools/perf/arch/s390'
  /bin/sh '/home/acme/git/perf/tools/perf/arch/s390/entry/syscalls//mksyscalltbl' 'cc' /home/acme/git/perf/tools/arch/s390/include/uapi/asm/unistd.h > /tmp/build/perf/arch/s390/include/generated/asm/syscalls_64.c
  make: Leaving directory '/home/acme/git/perf/tools/perf/arch/s390'
  $ head -5 /tmp/build/perf/arch/s390/include/generated/asm/syscalls_64.c
  static const char *syscalltbl_s390_64[] = {
	[1] = "exit",
	[2] = "fork",
	[3] = "read",
	[4] = "write",
  $ tail -5 /tmp/build/perf/arch/s390/include/generated/asm/syscalls_64.c
	[378] = "s390_guarded_storage",
	[379] = "statx",
	[380] = "s390_sthyi",
  };
  #define SYSCALLTBL_S390_64_MAX_ID 380
  $

Now to plug this into 'perf trace' proper.
