    gas -Z flag
    
    -Z is supposed to "generate object file even after errors".  It
    doesn't do so at the moment, unless you count a zero length object
    file as useful output.  Fixed for most targets as follows.
    I suspect avr and pru need target patches.
    
    	* output-file.c (output_file_close): Do a normal close when
    	flag_always_generate_output.
    	* write.c (write_object_file): Don't stop output when
    	flag_always_generate_output.
