Please someone update it.  For my reason why see
http://gcc.gnu.org/ml/gcc-bugs/2000-09/msg00385.html .  It would be nice to
not have my builds show up as armv4l-unknown-unknown-linux-gnu.

My understanding from what has been said in the past is that any
maintainer can update them from the master copies at
  :pserver:anoncvs@subversions.gnu.org:/cvs co config

If you want functionality which is diffent, you need to submit it the
people who keep the master copies up to date.  There is a link off of
http://sources.redhat.com/autoconf page, I believe.

Here is the relavant patch from subversions.gnu.org.
