imp 1a17c683b2 Better check for floating point type.
Use __riscv_flen instead of __riscv_float_abi_soft. While the latter works for
userland (and one could argue it's more correct), it fails for the kernel. We
compile the kernel with -mabi=lp64 (eg soft float abi) to avoid floating point
instructions in the kernel. We also compile the kernel -march=rv64imafdc for
hard float kernels (eg those with options FPE), but with -march=rv64imac for
softfloat kernels (eg those with FPE). Since we do this, in the kernel (as in
userland) __riscv_flen will be defined for 'riscv64' and not for 'riscv64sf'.

This also removes the -DMACHINE_ARCH hack now that it's no longer needed.

Longer term, we should return the ABI from the sysctl hw.machine_arch like on
amd64 for i386 binaries.
