Custom recipe for scipy with cythonrecipe

[advent-embedded]

Ive a stripped down functionality of scipy lfilter, i could successfully build my recipe when targeted for host PC x86_64, which gives shared object built via cython when i include the same recipe to kivy, i could pass the compilation step, while installation it stilll seeks to install at my development machine instead of ardroid folders.

 RAN: /home/sosdt002/kivy/plotgraph/.buildozer/android/platform/build/build/other_builds/hostpython3/desktop/hostpython3/native-build/python setup.py install -O2

  STDOUT:
running install
running build
running build_ext
running install_lib
creating /usr/local/lib/python3.7
error: could not create '/usr/local/lib/python3.7': Permission denied

reading around blogs i found running buildozer with root is not advise to overcome permission issue
