Alexander Kanavin cf1af6b384 pythonnative.bbclass, python3native.bbclass: export STAGING_INCDIR, STAGING_LIBDIR, PYTHON variables 
We patch Python's distutils modules to access STAGING_INCDIR/LIBDIR, so when
they are not set, scripts that utilize distutils (e.g. python-config) fail.
Several recipes need to export those manually to prevent such failures,
so let's do that in the class instead.

PYTHON variable is exported because otherwise autotools' python.m4
macro will pick up its own internal default, which may not be the version
that we want.

glib recipe in particular was previously using Python 2.x during build due to python.m4
defaulting to it - now it's using Python 3.x, and so needs a small fix in
deletion of *.pyc files.

subsystem that provide a framework for all things \
performance analysis. It covers hardware level \
(CPU/PMU, Performance Monitoring Unit) features \
and software features (software counters, tracepoints) \
as well."
