    hurd: fix clearing SS_ONSTACK when longjmp-ing from sighandler

    * sysdeps/i386/htl/Makefile: New file.
    * sysdeps/i386/htl/tcb-offsets.sym: New file.
    * sysdeps/mach/hurd/i386/Makefile [setjmp] (gen-as-const-headers): Add
    signal-defines.sym.
    * sysdeps/mach/hurd/i386/____longjmp_chk.S: Include tcb-offsets.h.
    (____longjmp_chk): Harmonize with i386's __longjmp. Clear SS_ONSTACK
    when jumping off the alternate stack.
    * sysdeps/mach/hurd/i386/__longjmp.S: New file.
