After consultations with the arm community, don't define softfp for
armv6. It's too ambiguous. We do use the softfp ABI for the moment on
armv6, but we allow floating point register use (and the compilers
will generate it). This is too ambiguous to use it as a decider for
which algorithms to use on the platform. Err on the side of caution
and not define it.
