[PATCH] D134337: [clang] [Driver] More flexible rules for loading default configs

Thanks Nick for the ping. Indeed, `rustc` allows to use a "target specification file" to create new targets that are not built-in, as a JSON file.

They are unstable though, since they are fairly tied to LLVM, and I think the Rust compiler team prefers to stabilize flags instead.

However, it would definitely be great for users and build systems if GCC, Clang and `rustc` could get together and decide on a new, common config file, even if it just covered the target specification.
