* oprofile 0.9.8: fix compilation on powerpcThomas De Schampheleire2013-03-241-0/+105
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.
