  tools lib api: Undefine _FORTIFY_SOURCE before setting it (2015-04-23 17:08:23 -0300)

----------------------------------------------------------------
perf/urgent fixes:

User visible:

- Enable events when doing system wide 'trace' and starting a
  workload, e.g:

   # trace -a sleep 1

  now it matches the pattern in 'record' and will show envents
  instead of sitting doing nothing while waiting for the started
  workload to finish (Arnaldo Carvalho de Melo)

- Disable and drain events when forked 'trace' workload ends
  making sure we notice the end of the workload instead of
  trying to keep up with the seemingly neverending flux of
  system wide events (Arnaldo Carvalho de Melo)

Infrastructure:

- Fix the build on 32-bit ARM by consistently use PRIu64 for printing u64
  values in 'perf kmem' (Will Deacon)

- Undefine _FORTIFY_SOURCE before setting it in tools/perf/api, fixing the build on
  Hardened Gentoo systems (Bobby Powers)
