Linker documentation patch

[Nick Clifton]

Hi Guys,

  I have applied the following supplimental patch to my previous patch
  updating the linker documentation.  This patch adds a note that
  other (non-GNU) compiler drivers may not use -Wl, as the linker
  command line option prefix.

  It also fixes a error in the documentation of the -n command line
  switch.  This option does not mark the text section as read-only.
  (It is marked as such by default, and the -N option can be used to
  make it read-write, but -n will not set it back to being
  read-only).   What it does do, however, is to turn off page
  alignment of the sections, so I have added this to the
  documentation.

Cheers
	Nick

	* ld.texinfo (Options): Remind users to preceed linker command
	line switches with -Wl, (or whatever is appropriate) if it is
	being invoked by a comnpiler driver program.
	Fix description of the behaviour of the -n command line switch.
