    ld/arc: Change default linker emulation for nps400
    
    If we are configuring for an arc/linux target, and --with-cpu=nps400 is
    used at configure time then change the default linker emulation to the
    nps specific version.  All of the alternative linker emulations are
    still available using the -mNAME option for ld.
    
    ld/ChangeLog:
    
    	* configure.tgt (arc*-*-linux*): Change the default linker
    	emulation based on --with-cpu selection.
    	* NEWS: Mention new configuration option.
