* hurd/intr-msg.c: Use INTR_MSG_TRAP macro from machine-dependent
 	"intr-msg.h" for special syscall code, instead of i386-specific asm.
	* hurd/hurdsig.c: Use INTR_MSG_BACK_OUT macro from
 	machine-dependent "intr-msg.h" before mutating thread state to
 	skip RPC.

	* sysdeps/mach/hurd/i386/trampoline.c: If PC is inside
 	_hurd_intr_rpc_mach_msg special syscall code, use real SP saved in
	%ecx.

	* Makeconfig (link-libc): New variable; use shared library if
 	available.
	(+link): Use it.

	* sysdeps/mach/hurd/fork.c (_hurd_fork_locks): Variable removed.
  	Instead, declare with `symbol_set_declare'.
	(fork): Use symbol_set_* macros for _hurd_fork_locks.  
	Use SS->thread instead of __mach_thread_self ().  Suspend all
 	other threads during task_create and port copying.
