I'm pretty sure lots of existing glibc architectures have code that's not 
covered by at present, even if there are 
configurations that could be added (e.g. building for another CPU variant) 
that would cover building that code.  That doesn't mean it's a good thing 
- more configurations to cover such code would be a good idea - but the 
present minimum for coverage is that at least each 
different ABI supported by glibcs is covered.
