A fairly common question, to which most times the answer is that you don't
need one.
You should only be using the OS ABI field if you are changing the meaning
of the ELF specifics for a processor (new relocs, for example) which a
linker not trained to recognise these would be unable to handle. It
shouldn't be used to represent things that are encoded in the instructions
inside sections (eg library calls specific to your OS, etc).
The ELF specs seem to find it very hard to express this, but if you read
it carefully, that is what they do say.
