* iree-llvm-target-abi: The flag is polulated to LLVM target abi.
-* iree-llvm-link-embedded: Generate the executable into a platform-agnostic ELF
-and use the ELF loader to load the library instead of using `dlopen` and `dlsym`.
-This creates the least overhead in the executable, and the simplest
-linker during codegen without dynamic library linkage; therefore, it will be the
