I ran into this last year.  And like Carlos O'Donell indicated in his
parallel email what's described here should solve your problem.
http://sourceware.org/ml/libc-alpha/2008-02/msg00007.html

In general, we don't re-run autoconf.  Generally Ulrich re-runs it and
checks the generated files into cvs when necessary.  But like my email
indicates, this can expose some discrepancies when there's a mismatch
between Autoconf versions used to generate the base configure files
and new configure files that you may need to generate from your own
new configure.in fragments.
