This is because redhat-rpm-config dehavior changed on F-10:
* Wed May 07 2008 Jon Masters <jcm at redhat.com> - 9.0.3-1
- Remove overwritten config.guess|sub files (testing).

This affects %configure macro. On F-8/9 %configure replaces
config.{sub,guess} in the tarball with /usr/lib/rpm/config.{sub,guess}
while on F-10 it does not.
