I'm not claiming it was the end of the world if someone accidentally 
breaks Voyager.

But Ingo wanted me to stop to sometimes compile test Voyager.

I'm still not getting the point why we should ever wait for James for 
doing things like
-       select HAVE_ARCH_KGDB
+       select HAVE_ARCH_KGDB if !X86_VOYAGER

And the other compile breakages we had recently weren't much worse.

I fully agree that it makes sense that Voyager problems should not be 
showstoppers and that James is the one capable and responsible of fixing 
non-trivial issues.
