documentation of Elf32_Sym.st_size
(Portable Formats Specification, Version 1.1):
 Many symbols have associated sizes. For example,
 a data object’s size is the number of bytes contained
 in the object. This member holds 0 if the symbol has
 no size or an unknown size.


_init_* seem to have a known size.
