Right, Windows has been doing stack clash protection since day #1, like for
example Tru64, so the option should just be a NOP on Windows.

This is the incompatibility of -fstack-clash-protection with Windows SEH.
Now the Windows ports always enable TARGET_STACK_PROBE, which means that
the stack is always probed (out of line) so -fstack-clash-protection does
nothing more.
