title: configure: error: C compiler cannot create executables - Buildozer kivy to android debuging
body: <p>ENTERING MY PROBLEM (they can skip it)
  Hello, I am trying to compile apk application, but I always have many problems due to lack of libraries and applications that my system does not bring and that are not mentioned in the buildozer and kivy requirements. I am stuck in this error after installing a lot of libraries to solve the previous ones. If you have the definitive guide of requirements to work with buildozer and kivy please add it as a complement to this answer. If you think it is better to format the system and start again to install only what is necessary, I am willing, as long as the information you give me is different from what is available in the official pages.</p>
  
  <p>PROBLEM
  I have: Ubuntu 18.04.1 LTS, Python 2.7.15rc1, Kivy v1.11.0.dev0, Buildozer 0.35
  Libraries imported in the .py: kivy, uuid, sqlite3</p>

  #    List as sections

  #    Each line will be considered as a option to the list.
  #    Let's take [app] / source.exclude_patterns.
  #    Instead of doing:
  #
  #[app]
  #source.exclude_patterns = license,data/audio/*.wav,data/images/original/*
  #
  #    This can be translated into:
  #
  #[app:source.exclude_patterns]
  #license
  #data/audio/*.wav
  #data/images/original/*
  #
  
  
  #    -----------------------------------------------------------------------------
  #    Profiles
  #
  #    You can extend section / key with a profile
  #    For example, you want to deploy a demo version of your application without
  #    HD content. You could first change the title to add "(demo)" in the name
  #    and extend the excluded directories to remove the HD content.
  #
  #[app@demo]
  #title = My Application (demo)
  #
  #[app:source.exclude_patterns@demo]
  #images/hd/*
  #
  #    Then, invoke the command line with the "demo" profile:
  #
  #buildozer --profile demo android debug
