The entries in the reference symbol table are used when loading the
module (both by the static and dynamic link editors) and if the module is
unloaded or replaced. Therefore all external symbols
(defined and undefined) are listed in the module's reference table. The
flags describe the type of reference that is being made. The constants
for the flags are defined in <mach-o/nlist.h> as they are also used for
symbol table entries.
