I find it extremely unlikely that many well-thought-out extensions would
be appropriate for GNU systems using the Linux kernel but not for GNU
systems using Hurd or other kernels - the only such cases would be for
things very closely related to kernel functionality. There is a strong
presumption that toolchain configuration should apply to all GNU systems
rather than being specific to GNU/Linux without good reason.
