LL-NDK, VNDK-core, VNDK-SP libraries are exported to make as SOONG_LLNDK_LIBRARIES, SOONG_VNDK_CORE_LIBRARIES, and SOONG_VNDK_SAMEPROCESS_LIBRARIES. This can be used to auto-generate ld.config.txt from a template. Bug: 64013660 Test: BOARD_VNDK_VERSION=current m -j successful Test: check out/soong/make_vars*.mk and look for SOONG_*_LIBRARIES Merged-In: I0f4c5d05d9cd28c3fc9fdcca6ce0e6eaeaacbe8d Change-Id: I0f4c5d05d9cd28c3fc9fdcca6ce0e6eaeaacbe8d
