Pure soft-float on MPC8xx anyone?

Did anybody on this list succeed in building a soft-float toolchain for
the Freescale MPC8xx series?

Reason i'm asking is that i built a gcc-4.0.1-glibc-2.3-5-binutils-2.16.1
toolchain with -mcpu860 and --without-fp, however a compiled busybox still
causes "bad emulation" exceptions.

I know about the "remove memset.S" trick due to different cache-lines (however,
i don't fully understand the background) and did that. Maybe something more
needs to be patched away?

Oh, and i didn't compile userspace seperately but simply copied the /lib folder
crosstool produced to the target; looking at the compiled-in paths i guessed
that should be possible and working... Bad idea?

Best regards,
