+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.
