Could you please help me better understand the intended setup?

Do you mean adding `macro_value` in include/sys/xattr.yaml or creating an include/llvm-libc-proxy/xattr_proxy.yaml instead of this header? If the former, what is the expected way to use these macros in a unit test, including <sys/xattr.h>?

I tried looking around for existing `macro_value` usage, and I saw include/llvm-libc-proxy/elf_proxy.yaml and uses in top level include/ yaml files, but I could not yet find one that is also used in a unit test.
