most of the soft float vs hard float comparisons "out there" are flawed
because they at the same time compare (ancient) armv5 code with floating
point *emulation* with armv7 code using the VFP and hardfp calling
convention.

comparing *only* soft vs hard calling convention yields much more
reasonable results:
