Target attributes must be implying optimisation attributes. Bug depends also
on --with-{arch,tune,fpmath} settings. I'll try and reproduce it on
x86_64-linux, it should be possible if I choose the right settings - will reply
again later.

No, it's not related to the backend lto support at all; the sorry comes from
the lto output streamer. It does depend on the backend's attribute handling
though.
(See also PR41201, vaguely related.)
