This is not how an ELF runtime linker works.  Run ldd on a binary --
this lists all the shared object files that are mapped into the
address space of the process before main() is called.  Symbol
references are not necessarily resolved at that time, unless you
define LD_BIND_NOW or are using prelinking.  There's really no
method of doing "lazy linking" as you suggest with C, since it
would either fail (such as with global variables in libraries) or
be required to violate the ISO standard, such as taking the address
of a function.
