[patch, fortran] Put lang.opt back in ASCII collating order

[Brooks Moses <brooks dot moses at codesourcery dot com>]

There's a comment at the top of lang.opt that says, "Please try to keep 
this file in ASCII collating order."  Currently, it's quite out of 
order; the following patch fixes this.

---------------------------------------------------------------
2006-11-15  Brooks Moses  <brooks.moses@codesourcery.com>

	* lang.opt: Rearrange entries back into ASCII order.

---------------------------------------------------------------

Regression tested on i686-pc-linux-gnu.  Ok for trunk?
