Clang has some gcc-config code which should migrate to [configuration file](https://clang.llvm.org/docs/UsersManual.html#configuration-files). See https://github.com/llvm/llvm-project/issues/57570 for detail. gcc-config needs to provide Clang configuration files. Reproducible: Always
Not sure which path gcc-config should install the config file to. Presumably the default config file we install with clang should use "@gcc-config.options" or similar to include a small config file gcc-config would install. Also, to which path? /etc/clang?

We discussed this in #gentoo-llvm and we concluded gcc-config should only update the file if it exists.
Little more context: I'm not 100% sure this idea is workable, as the config file would also force host's install dir when working with a --sysroot. If it turns out that we have to revert it, I'd prefer that gcc-config wouldn't recreate the file once clang-common removed it.
