title: Install a python module from OpenWrt makefile
body: <p>I need to write an openWrt Makefile which installs a module into python, using setuptools, i.e. calls:
  python setup.py install</p>
  
  <p>I have setup.py file in my package.</p>
  
  <p>Failed to find the answer in OpenWrt package build referrence</p>
  
  <p>I hope there's some infra structure for setuptools in OpenWrt? I suppose I have to include some .mk file 
  $(call include_mk, python-package.mk)?</p>
  
  <p>and then call some target from it?</p>
  
  <p>Will appreciate any sample Makefile/manual</p>
