I have noticed in linux-next that the flag triggers an ICE when
building the docs with `O=` -- reduced and reported to upstream here:

    https://github.com/rust-lang/rust/issues/138520

Moreover, the flag was only added (to `rustdoc`, not `rustc`) starting
with 1.81.0, so we couldn't pass it anyway unconditionally to
`rustdoc` (it is OK for `rustc`).

In the meantime, the easiest to avoid both issues is to avoid passing
the flag when building docs -- I have sent a patch:

Cheers,
