top level configuration: Make autoconfier

[Nathanael Nerode <neroden@doctormoo.dyndns.org>]

This is a cosmetic change.  It allows Makefile.in to look more autoconfy, by 
replacing (some of) the sed statements in configure.in with sed statements 
which substitute for autoconf-type patterns.  This will save on the number
of meaningless changes to Makefile.in when full autoconfiscation happens.
It also makes it marginally harder for accidental missubstitutions to happen.

Tested by configuring on i686-pc-linux-gnu; the resulting Makefile was 
unchanged.

I'm going to be doing a lot more of this before autoconfiscation.

2002-09-25  Nathanael Nerode  <neroden@gcc.gnu.org>

	* Makefile.tpl: Rewrite substituted lines to look autoconfy.
	* Makefile.in: Regenerate.
	* configure.in: Rewrite sed statements to look autoconfy.
