I just referenced the denx patch. So I don't have the exact knowledge obout it. I guess the step is for omitting floating point because MPC860 doesn;t support it.I think supporting floating in kernel by floating-point interrupt,
and compile glibc without -msoft-float or -D_SOFT_FLOAT is better.But the guys in this list doesn't seam to recommand it.

That was my mistake. I meant...
#ifeq ($(subdir),math)
#libm-support += fenv_const fe_nomask
#endif
