That the binary packages referenced by the .dsc file include at least
one package that has Architecture: i386, at least one that has
Architecture: amd64 and at least one that has Architecture: all.

introducing the feature includes this hunk:

+    if (grep($_ eq 'any', @sourcearch)) {
+       # If we encounter one any then the other arches become insignificant.
+       @sourcearch = ('any');
+    }
+    $fields->{'Architecture'}= join(' ',@sourcearch);
