No, the CPU has no FPU. But the kernel is able to emulate the FPU, so it's just slow but it works. I just didn't manage to create a i486 toolchain with soft-float. See also http://old.nabble.com/i486-toolchain-with-softfloat-td31879412.html. The hint about multilib didn't help either. Do you have any ideas?
