PIL recipe is broken

[lipi]

Trying to use PIL but it can't find symbols when loading _imaging.so

Reproducible with a simple test app, see https://gist.github.com/lipi/4381f5feb9b39a20a074c18537e57fb3

Built it using

p4a apk --requirements=kivy,pil --private . --package=org.example --name="pil-test" --version=0.1 --bootstrap=pygame
