This is almost identical set of patches recently done for s390.

With this, user can run perf trace without libaudit on powerpc
as well. Ex,

  $ make
    ...     libaudit: [ OFF ]

  $ ./perf trace ls
    0.221 ( 0.005 ms): ls/43330 open(filename: 0xac1e2778, flags: CLOEXEC   ) = 3
    0.227 ( 0.003 ms): ls/43330 read(fd: 3, buf: 0x3ffff9c4d678, count: 832 ) = 832
    0.233 ( 0.002 ms): ls/43330 fstat(fd: 3, statbuf: 0x3ffff9c4d4b0        ) = 0
    ...

  $ ./perf trace -e "open*" ls
    0.000 ( 0.014 ms): ls/43342 open(filename: 0x793d8978, flags: CLOEXEC   ) = 3
    0.038 ( 0.006 ms): ls/43342 open(filename: 0x793f2778, flags: CLOEXEC   ) = 3
    ...

Ah, I already had to update the unistd.h copy to catch some new syscalls
for s/390 :-)
