This looks really odd. Then again, this is Darwin specific, so the
rules are different.

I'd be surprised if this is the only case that gets it wrong, and as
fix goes, this is pretty vague.

O Linux we default to ARMv4T for soft-float and ARMv6Z for hard-float.
We also don't have "thumbv*" as we tend to normalise to "armv*" so not
to get that wrong. I'd expect a more thorough fix, and re-using a test
that already exists for that.

cheers,
