Log message:
ELF security enhancement: put .rodata into it's own load section instead of putting it with the text. This removes the execute permission from readonly data. This constrains the executable region to portions of the executable which need to be executable. Note: not all processors or mmus are capable of -X protection at the page level, but should handle ELF images which specify specific RWX protections on each section.
