I totally missed it; this change was a part of a downstream patch we were using for building Fuchsia toolchain and it predates this option. Using this option, I can override the dialect only for our build, which is perfectly fine for Fuchsia since we default to C++14. I'd be happy to abandon this patch unless you want to persist that setting for musl?
