 I think we could simply force --without-system-libs (or at least for C++ 
libs) when --enable-debug is used and that could do. I don't how much is 
_GLIBCXX_DEBUG is worth, but --without-system-libs doesn't look like that big 
price to pay.

 How would that work? The non-debug 3rd-party lib will always use non-debug 
version of list and that means we'd have to manually somehow use non-debug 
version of list as well when interfacing with the library. That sounds pretty 
unfeasible in practice to me.
