- Pass a CROSS_COMPILING variable to setup.py
- The setup.py script in the Python source code plays a significant role
- in the Python build process. It is responsible for building all the
- modules and extensions, and due to this, does various checks that need
- to be adjusted when we are cross-compiling.
- For that reason, this patch makes sure that a CROSS_COMPILING variable
- is passed in the environment of the setup.py script. Later patches in
- the stack make use of this variable.
