+- make doc packages noarch. no need to have those per arch
+- ensure that the src rpms are named per build flavor:
+  You might now ask why. Good question:
+
+  1. the spec file during the build get patched. `@BUILD_FLAVOR@`
+     gets replaced with the value. which means the src rpm between
+     build flavor builds is not identical. Also the last built
+     src.rpm will be published. with different content and runtime
+     requires (aka our BuildRequires).
+
+  2. for historical reasons the internal dependency tracking goes
+     via the src.rpm package. So without having differently named
+     src.rpms the build cycle we were trying to solve was not
+     actually solved. So we append a suffix to the Name attribute
+     in the preamble now.
