On x86, it's stored through src/arch/x86/lib/id.inc

It's a somewhat arcane format (historically grown), and is typically

0x80 bytes before the end of the image. The last 4 qwords are the .long
values from which you can calculate the address of the version field

test_id_section() and its caller provide an example for parsing that.
