"""Bazel flags for architecture / platform combinations.

Every platform has the --apple_platform_type flag set (macOS uses 'darwin'
instead of 'macos').

macOS and iOS use the base --cpu flag, while tvOS and watchOS use --tvos_cpus
and --watchos_cpus respectively.

For iOS apps, the --watchos_cpus flag is also set separately.
