[committed] More cleanup in configure.ac

[neroden at twcny dot rr dot com (Nathanael Nerode)]

Bootstrapped i686-pc-linux-gnu, committed.  This is more of the "untangle
the configure file so ordinary mortals can understand it" work.  :-P

	* configure.ac: Rearrange some threading code for clarity;
	add section comment.
	* configure: Regenerate.
