... a function pointer to a function that takes no argument and returns the real function pointer to use ...

It would be useful to have some parameters: a pointer to the symbol table entry for the symbol in question (and the string table, ...), and a pointer to the dynamic linker context (search path: chain of struct link_map *) that applies. Then the same intercepting function could handle multiple names (there are many str* and mem* functions, for instance) and might be able to handle better some special cases such as compatibility matching, etc.
