nios2 uses software single step, so GDB is unable to single step to
the signal handler.  In order to reflect this, teach
can_single_step_to_signal_handler to return zero for nios2 target.

Patch is checked in.

	* lib/gdb.exp (can_single_step_to_signal_handler): Return zero
	if target is nios2-*-*.
