Hiding this behind is_android would require an
is_defined(enable_resource_whitelist_generation) check, would that be
preferable? Everything besides setting enable_resource_whitelist_generation is
already behind is_android already.

[Dirk Pranke, 2016/08/29 18:15:11]

is_android is a global variable, so why would that require an
is_defined(enable_resource_whitelist_generation) check?

Alternatively, if enable_resource_whitelist_generation is an android-only
concept, we could make this a toolchain arg.

At any rate, we can also land and iterate, to unbreak things.
