cirros-testvm/src-cirros/buildroot-2015.05/package/python/010-fix-python-config.patch

   1 Add a backport of http://bugs.python.org/issue16235 so we can use
   2 python-config for cross builds.
   3 This basically replaces the python version of python-config with a pure-shell
   4 version that's already preprocessed when installed and doesn't depend
   5 on the sysconfig import that usually leads to bad data/results.
