What exactly is the problem?  Is the gfortran driver invoking a subprocess 
with separate "-l" and "gfortran" arguments?  The code in gcc.c that does

    case OPT_l:
      /* POSIX allows separation of -l and the lib arg; canonicalize
     by concatenating -l with its arg */
      add_infile (concat ("-l", arg, NULL), "*");
      do_save = false;
      break;

is supposed to act after lang_specific_driver has modified the command 
line, and should avoid that issue.  Or is something processing the 
"Driving" line?  I thought that line was human-readable output (complete 
with translation of the word "Driving"); it certainly isn't unambiguous in 
the presence of arguments containing spaces or newlines.  If there are 
defined requirements on the "Driving" line, the code that outputs it 
should be adjusted to follow those requirements.
