How, exactly? How did you arrange your sources? How did you configure?
Did you try reading the docs first?

Here, you may find this useful:

http://gcc.gnu.org/simtest-howto.html

I'd suggest following those directions exactly at first. Once you have
success, you can try variants.

All you should have to do is specify --target=powerpc-eabisim.

Please, crosstools mail should just be posted on the crosstool list.
