The split GCC package set (`gccNGPackages`, opted into with `useGccNG`) builds each runtime library separately, so the compiler is configured independently of `libgcc` and `libstdc++` and the two can disagree about threading. Rather than probe the compiler, those packages read the answer from the package that decides it, through the same `passthru.threadModel` that `glibc`, `musl` and NetBSD's `libc` already declare. MinGW's libc has none of its own beyond the Win32 API, so it declares `win32`. Past that the answer depends on which threading library a toolchain is built against, so `mcfgthreads` declares `mcf` and `winpthreads` `posix`. Nothing reads either yet. The headers-only build is marked as such rather than given a model: it exists only to get the libc compiled, and runtimes built against it stay single-threaded.
