I'm completely thinking along your lines here. I think we should focus 
on the end result, not the specific implementations details. I've been 
thinking about exposing a configure option like this:

--with-debug-symbols=none (for #1)
--with-debug-symbols=internal (for #2)
--with-debug-symbols=zipped (for #3)

but perhaps with better names. I also imagine there might be a use case 
for yet another option,
#4. Debuggin information stripped from the binaries, but not zipped

expressed like this
--with-debug-symbols=external

And then this would be the only user interface needed, and the rest of 
the current set of not-really-clear flags can be hidden inside the 
configure script.

  For compatibility reasons, the default would be 
--with-debug-symbols=zipped (which is called "FDS" here), just as we 
currently do, but distributions would just need to add a 
--with-debug-symbols=internal to get what they want.
