Presumably the right way to do this would be:

"make clean reconfigure ..."

otherwise you could get some kind of weird hybrid build. I'm not sure 
that every change in spec.gmk, for example would force a recompile of 
everything that depended on something in there. But perhaps it does?

Sometimes I've re-run configure with the exact same args and I get a 
warning about doing this over an existing configuration ?? At which 
point I either do a dist-clean or "rm -rf ...".
