I've not actually double checked that everything is wired up properly
but I believe these days this should actually pick up asm/ptrace.h from
the headers_install target so a current kernel copy.  We ought to be
able to remove the local definition of struct user_gcs I think, there's
still some weirdness with the NT_ definitions I can't remember but the
struct should be fine.
