| 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. |
