 I assumed it was implied where it mattered. Using --enable-debug/dbgutil is 
for developer builds, isn't it?

 Strictly speaking, no Jenkins build does that except for the Linux GCC 
release one, as all the others build with --enable-dbgutil, so I find this 
argument weak. In practice it seems it's the tinderboxes that check this (if 
at all).
