Subject: [PATCH] Feature: Add ability to avoid source packages from building
 on specific architectures

Example:

<Source>
    <Name>psyco</Name>
    ..
    ..
    <ExcludeArch>x86_64</ExcludeArch>
</Source>

will avoid the package psyco from building on systems where pisi.conf->architecture == x86_64
