Makefile: fix Python 3 site packages when using PYC_ONLY
PATCH 1/1 Makefile: fix Python 3 site packages when using PYC_ONLY
The Python 3 standard lib is compiled into PYC bytecode using a pre-PEP-3147 mode (.pyc files beside .py files; no __pycache__) when BR2_PACKAGE_PYTHON3_PYC_ONLY is enabled. However, site packages installed with setuptools/distutils are compiled following PEP-3147. When BR2_PACKAGE_PYTHON3_PYC_ONLY is on, .py source files are removed and Python 3 (target) will not look into __pycache__ directories without associated .py files.
Python 2 does not suffer from this since PEP-3147 seems to be implemented in Python 3 only.
This commit fixes this by compiling Python 3 site packages using a pre-PEP-3147 mode after they are installed and then removing __pycache__ directories.
