[PATCH v3 0/8] support profile-optimized build for Python

[Markus Lehtonen <markus.lehtonen@linux.intel.com>]

Third incarnation of enabling profile-guided-optimization (PGO) for Python. The
patchset is significantly simplified from the previous version, mainly because
Python 2.x is not supported, and because of that, there is no need to install
packages under modified (opt/) prefix. Also, RSS made libpython soname mangling
unnecessary.

The last patch of this changeset is not obligatory after the changes since v2.
However, it will remove some hacks that should not be needed.

Changes since v2:
- support for Python 2.x dropped
- profiling recipe name changed from python-profile-opt3 to python3-profile-opt
- python3-profile-opt now uses standard 'usr/' prefix, and thus, it now also
  rconflicts with "regular" python3
- libpython name mangling in python3-profile-opt removed
- all patches to python-pgo-image squashed into one
