It removes 2 precompiled binaries used which are now
can be crafted with the use of yaml2obj.

-## many-sections.elf-x86_64 is a file that was generated to simulate

+## Here we simulate an object with more than ~65k sections and check how we dump it.
+## When an ELF object has SHN_LORESERVE (0xff00) or more sections, its e_shnum field
 ## should be zero and sh_size of the section header at index 0 is used

 ## at index 0 is used to store the value.
