commit 99ee4d26dc07c3eadfbf6793db26ef9dfb1551e5

    hurd: Fix static initialization with -fstack-protector-strong
    
    When linked statically, TLS initialization is not achieved before
    mach_init and alike, so ssp accesses to tcbhead's stack_guard would
    crash.  We can just avoid using ssp in the few functions needed before
    TLS is set up.

    	CFLAGS-RPC_vm_map.o, CFLAGS-RPC_vm_protect.o,
    	CFLAGS-RPC_i386_set_gdt.o, CFLAGS-RPC_i386_set_ldt.o,
    	CFLAGS-RPC_task_get_special_port.o): Add $(no-stack-protector).
    	* hurd/Makefile (CFLAGS-hurdstartup.o,
    	CFLAGS-RPC_exec_startup_get_info.o): Add $(no-stack-protector).
