add122a828
Adds dylib support for vendor and recovery images. This changes the default linkage for vendor and recovery images to dylib, which matches the platform default linkage. This also means that by default, dylib-std variants are used for rlib dependencies. Bug: 204303985 Test: Soong tests. Test: m dist vendor-snapshot Test: RECOVERY_SNAPSHOT_VERSION=current m dist recovery-snapshot Change-Id: If84074b8615a70c45e7e162abeb853dc8c34d49a
