<p>Some uses of external symbols do not need to be bound immediately.
Instead they can be lazily bound on first use. The lazy_bind
are contains a stream of BIND opcodes to bind all lazy symbols.
Normal use is that dyld ignores the lazy_bind section when
loading an image. Instead the static linker arranged for a
lazy pointer to initially point to a helper function which
pushes the offset into the lazy_bind area for the symbol
needing to be bound, then jumps to dyld which simply adds
the offset to lazy_bind_off to get the information on what
to bind.</p>
