It just finished building.  Indeed, the 'vfp' patch fixes the
'printf("%f\n", 0.5); prints 0.000000' and general 'floating point
is broken' on my big-endian hardfloat FPA ARM platform.

It's definitely needed for hardfloat.  So I'd think it's needed for
big-endian systems in any case, and for VFP on little-endian systems
too.  Someone would have to verify that though.
