Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

User visible changes:

  - When handling perf_event_open() returning EBUSY and not being able to opendir
    the procfs mount point we would tell the user that the oprofile daemon was
    found by returning -1 on as the return for a bool function, oops, fix it,
    found with Coccinelle. (Peter Senna Tschudin).

  - Fix per-pkg event reporting bug in 'perf stat'. (Stephane Eranian)

Developer visible changes:

  - Fix missing prototype for function provided when it isn't present in the
    libelf present, fixing the build on RHEL/CentOS 5.1 systems, for instance.
    (Arnaldo Carvalho de Melo)

  - Detect if the gcc and libnuma have the features needed to avoid requiring
    the use of NO_LIBNUMA and/or NO_AUXTRACE to build on older systems.
    (Arnaldo Carvalho de Melo)
