I think you are right. I initially avoided that because one of the values is
`Default` which is meant to defer to the triple, but in the constructor of
`ARMBaseTargetMachine` it sets the internal `Options.FloatABIType` to one or
the other based on the passed in option and the triple, so it should be correct
to just use that. I was testing with things like `--target=arm-none-eabi
-mcpu=cortex-m0 -mfloat-abi=hard` and seeing the error trigger, so something
else in the frontend may be generating a different triple that makes this
"work".
