Thomas De Schampheleire 99fc6299db oprofile 0.9.8: fix compilation on powerpc
The oprofile build was broken on powerpc since version 0.9.8.
This was detected in several autobuilds, like
http://autobuild.buildroot.net/results/6f6c02d18495907d50fcdfc6003ac20d493c55fe/

Thomas Petazzoni had some fixes pending in his own tree, and this patch is
partially based on this work (credits to him). Here is an overview:
- I took over (and fixed) the oprofile.mk changes, except for the powerpc-
  specific part. For powerpc, there is a new dependency to libpfm4.
- I reimported those Yocto patches that were specific to the ppc build
  issues, but left out the other ones. Those can be added in separate
  commits.

OProfile is a system-wide profiler for Linux systems,
capable of profiling all running code at low overhead.
OProfile is released under the GNU GPL.
It consists of a kernel driver and a daemon for collecting
sample data, and several post-profiling tools for turning
data into information.
OProfile leverages the hardware performance counters of the
CPU to enable profiling of a wide variety of interesting
statistics, which can also be used for basic time-spent
profiling. All code is profiled: hardware and software
interrupt handlers, kernel modules, the kernel, shared
libraries, and applications.
