- Add distutils fix for PEP 3147 issue
- Python 3 has a new standard for installing .pyc file, called PEP
- 3147. Unfortunately, this standard requires both the .py and .pyc
- files to be installed for a Python module to be found. This is quite
- annoying on space-constrained embedded systems, since the .py file is
- technically not required for execution.
- For the Python standard library, our Python 3 package already contains
- a patch named python3-004-old-stdlib-cache.patch, which allows to
- disable the PEP 3147 installation.
- But that lives the distutils/setuptools package an unsolved
- problem. This patch therefore adds a new patch to Python, which makes
- distutils package use the traditional installation path when byte
- compiling, rather than the PEP 3147 installation path. Since
- setuptools relies on distutils internally, it also fixes setuptools
- based packages.
