[build] More --enable-threads cleanup

[Rainer Orth]

In my last --enable-threads cleanup patch

	[build, doc] Cleanup --enable-threads support
        http://gcc.gnu.org/ml/gcc-patches/2011-04/msg00735.html

I missed another opportunity, handled by this patch.

Bootstrapped on i386-pc-solaris2.11 (not that it's relevant).  Ok for
mainline?

	gcc:
	* configure.ac (enable_threads): Remove irix; add lynx, tpf; sort list.
	* configure: Regenerate.
