### What needs to get done Allow using the value "all" when creating a ProjectInfo. When this happens, fail during environment expansion if the user uses `$CRAFT_ARCH_TRIPLET_BUILD_FOR` and fail during part loading if any of the parts can't create platform-independent results. (This will require adding something to the plugin to determine this. For most plugins it's a simple True/False, but for the npm plugin this depends on the value the user set for `npm_include_node`). We don't have to worry about anything in override scripts for determining whether the result can be platform-independent. Only consider the direct output of the plugin. ### Why it needs to get done Make creating platform-independent parts easier.
