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.

Based on patch by Benoit Mauduit. Now that we can build binutils for
the target with external toolchains, oprofile is also available.

Convert the oprofile target to select the new libbfd staging/target
option to avoid a huge target binutils for a simple task.

oprofile depends on binutils_target, but binutils_target fails to
build with external toolchains because the binutils version has not
been choosen. As the fix is not trivial, let's just disable oprofile
in external toolchain builds for the moment.
