Add soft float fallback to enable building from libs with softfp ABI enabled. Code built with `soft` and `softfp` `float-abi` options can be linked together as they both use the same soft-float ABI and generate functions to pass floating-point arguments to integer registers. This is contrary to the `hard` option where floating-point arguments are passed directly to FPU registers. `softfp` additionally allows using hardware floating-point instructions instead of emulated ones.
