[PATCH] [ARM] Handle conflicts between -mfpu and -mfloat-abi options

[Renato Golin]

Overall looks good, but I think that this change will also change other ARM architectures (v4~v7) and would be good to add the same login on the prev8 side of things.

Also, can you generate the diff with "-U99" so we can see the rest of the context?

Thanks!

why not put this at the end of the argument list and make it NULL by default?
