With project prefix mapping on, only directories one level below OBJROOT and BUILD_DIR are mapped (PROJECT_TEMP_DIR and BUILT_PRODUCTS_DIR). Paths next to them still end up verbatim in the compile cache key, for example the generated module maps of package targets in `$(OBJROOT)/GeneratedModuleMaps-<platform>`, or an in-build macro plugin in another platform's products directory. Map OBJROOT to `/^intermediates` and BUILD_DIR to `/^products`. The existing, more specific mappings still take precedence.
