I used Dan's crosstool scripts for the MPC860 with gcc-3.3.3 and glibc-2.3.2.  The PowerPC gcc build does presumably know about the e500 core and any variations it may have from other PowerPC variants.  I would start with Dan's MPC860 setup and adjust it from there to build for the MPC85xx.

Care to contribute an mpc85xx.dat and demo-mpc85xx.sh?

Also, for anyone wanting to try building gcc/glibc with crosstool
on cygwin, be sure to use version 0.28-pre13 or later,
(it's at http://kegel.com/crosstool/crosstool-0.28-pre13.tar.gz)
and if you happen to have cygwin 1.5.9, you may need to
replace your cygwin1.dll with the one from
http://cygwin.com/snapshots/cygwin1-20040325.dll.bz2
to get around a crash bug; alternately, you can wait
for cygwin-1.5.2 to be released.
