I did wonder about that "or", thanks for clarifying.

A different (and shorter) patch that solves my problem is to instead
qualify the hwcap_allowed test in sparc_ip with "&& architecture_requested",
but I'm guessing from your other comments that the behaviour change when
no -A was given is intentional so I won't try to push it upstream.
