Allow local edition of recipes. Recipe replacing standard one is located in a
directory defined in an environment variable P4A_{name}_DIR, where {name} stands for the recipe name. P4A_force_build set (True) forces local recipes rebuild, other (standard download) recipes are reused. On linux P4A downloads and builds are stored in ~/.local/share/python-for-android/ (no change), to initialize p4a build erase the directory.
