Build libjnigraphics, imagedecoder_fuzzer on host
Bug: 142252770
Bug: 169137236
Bug: 169139756
Test: SANITIZE_HOST=address make imagedecoder_fuzzer
This will allow running the fuzzer much faster in order to find bugs. It
also allows running with ASAN to help find memory leaks.
Some symbols (e.g. ABitmap, AAssetStreamAdaptor) rely on
Android-specific features, so disable them when building on the host.
This still allows using the core features of AImageDecoder.
This requires a change in frameworks/native
(Iefdb4132d6f10f9164be85f4dc6e11883f6fd37e).
Disable detecting ODR violations when building with ASAN (which is how
host builds are built). Without this change, the host detects the
following:
=================================================================
