I was following what the other targets do, but I could replace it with a has include if needed.

Updated, guess we'll see if this passes CI.
Summary: The `langinfo.h` header is a POSIX extension, so ideally we would be able to build the C++ library without it. Currently the LLVM C library doesn't support / provide it. This allows us to build the C++ library with locales enabled. We can either disable it here, or just provide stubs that do nothing as in llvm#106620.
