Configure differences on rebuild?

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

I regenerated libjava/configure, and got different results.  The *.$ac_ext
bit is not significant (Debian local modification to autoconf 2.13).
But the other bit I can't quite figure out.  :-)

I'd like to commit this change if it's OK because I'm going to be
doing work on the toplevel config/*.m4 files, and every spurious difference
causes confusion when doing that.

(libjava)
	* configure: Regenerate.
