To support linker-specific property, sys.linker.* has been defined as linker_prop. This will have get_prop access from domain so all binaries can start with linker using proper property access level. Bug: 138920271 Test: m -j && Confirmed from cuttlefish that get_prop errors are no longer found Change-Id: Iaf584e0cbdd5bca3d5667e93cf9a6401e757a314
