[patch] Remove TEXT_SECTION.

[Kazu Hirata <kazu at cs dot umass dot edu>]

Hi,

Attached is a patch to remove TEXT_SECTION as it is unused.

AFAICT, TEXT_SECTION used to be a string constant like ".text".  The
current C statement version of TEXT_SECTION was introduced by

  http://gcc.gnu.org/ml/gcc-patches/2001-08/msg01043.html

Then this patch 

  http://gcc.gnu.org/ml/gcc-patches/2003-06/msg00697.html

removed all uses of TEXT_SECTION.

Tested on i686-pc-linux-gnu.  OK to apply?

	* system.h (TEXT_SECTION): Poison.
	* varasm.c (text_section): Don't use TEXT_SECTION.
	* config/sh/sh.c (sh_file_start): Fix a comment typo.
	* doc/tm.texi (TEXT_SECTION): Remove.
