The idea is that after step 3.5 is executed, Emacs won't be using 
deprecated malloc-related symbols. Emacs may supply its own malloc 
implementation that provides the deprecated functionality, presumably 
using Emacs-specific names, but Emacs won't be using glibc's 
__malloc_initialize_hook, malloc_set_state, etc. As I understand it, 
this should satisfy Florian's concern.
