    rtld-elf - Allow dynamic (late) relocations to relro section
    
    * Normally the relro section is mprotect()ed to read-only after normal
      load relocations.
    
    * It appears that some programs can issue dynamic relocations at
      run-time to such sections.
    
    * If the relro mprotect has been done on an object, temporarily mprotect
      the object back to RW to execute the relocation, then mprotect it back
      to RO.
