 #  use_chromium_linker - Enable the content dynamic linker that allows sharing the
 #    RELRO section of the native libraries between the different processes.
 #  load_library_from_zip_file - When using the dynamic linker, load the library
 #    directly out of the zip file.
 #  use_relocation_packer - Enable relocation packing. Relies on the chromium
 #    linker, so use_chromium_linker must also be enabled.
 #  enable_chromium_linker_tests - Enable the content dynamic linker test support
 #    code. This allows a test APK to inject a Linker.TestRunner instance at
 #    runtime. Should only be used by the chromium_linker_test_apk target!!
 #  never_lint - Set to 1 to not run lint on this target.

+#  app_manifest_version_name - set the apps 'human readable' version number.
