Description of problem:
graphviz's configure.ac mis-applies canonicalization. The authors mix up $target
and $host (cf. info autoconf). Where $host should be used, they use $target.
This causes autoconf to apply "seemingly broken" transform rules.
(The rules autoconf generates are correct, the configure script however is broken).

This is the cause for graphviz.spec having to work-around these bugs by
overriding transform during 'make install'

Version-Release number of selected component (if applicable):
graphviz-2.2.1


Additional info:
graphviz-2.4.x (rawhide) suffers from the same issue.
