A number of cases have cropped up where things like documentation
builds fail with out of tree builds because tools like Doxygen like
encoding the build path into the documentation metadata.
This causes failures in Koji and other places where noarch documentation
subpackages from archful packages fail because they fail the comparison
check due to this.
