Or we could decide that "position-independent" should always be
hyphenated as it's a commonly established adjective. I'm not arguing
in favour of that, but it's how it's used in some of the docs already.

We have several of uses of "position independent executable" and
one "position independent data" which should be hyphenated.

Ignoring all the uses of "position-independent code" that already have
a hyphen we're left with the following and none of them is correct!
