When parsing ELF, reading the number of sections needs special handling.

From the elf man page:

              If the number of entries in the section header table is
              larger than or equal to SHN_LORESERVE (0xff00), e_shnum
              holds the value zero and the real number of entries in the
              section header table is held in the sh_size member of the
              initial entry in section header table.  Otherwise, the
              sh_size member of the initial entry in the section header
              table holds the value zero.
