platform_build/core/clang/arm64.mk
Ying Wang 1f9828387d Refactor llvm_config.mk and support the 2nd arch
1. Following the setup of gcc in build/core/combo/,
we added the [HOST|TARGET]_<arch>.mk clang config files,
and load only the configs needed by the current product.
2. Added support for the 2nd arch.
