support profile-optimized build for Python

This patchset makes it possible to build Python with profile-guided-optimization (PGO) enabled. Both Python 2.7 and Python 3 as well as native and target recipes are supported. The patchset is basically identical to the two RFC patchsets (separate for Python 2 and Python 3) I posted earlier
- I just rebased those on top of the latest master.

The following changes since commit def3800c7e58d9d1b54ea1df27b190a0f6d1d544:

layer.conf: bump version for change in eSDK selftest behaviour (2017-02-19 09:38:59 -0800)
