Device binaries currently are linked statically by default. Instead we should be linking these dynamic by default. To avoid conflicts when manually specifying rlib dependencies on modules, we always link libstd dynamically for all device modules except static libraries. This removes the "prefer_dynamic" property entirely to avoid confusion. Bug: 165161105 Test: m profcollectd is built dynamically. Test: cd external/rust/; mma Test: cd external/crosvm/; mma Change-Id: I25ac897040acbcc2d97c791a33e8e01610632272
