How to build cross compiler

[sarae@hss.hns.com]

Hi,
       I want to build a cross compiler which runs on Red Hat 6.2 -- intel
 and generates executables which are run on target Red Hat 6.2 -- powerpc.

Please suggest me some documents for this... FAQs ?
I think, i need to build :

1) Gcc with --target=powerpc-linux
2) Glibc with gcc obtained in step 1.
3) Gcc with Glibc obtained in step 2

Is this correct ?.
Has anyone built a similar cross compiler.

Please help me out.

Thanks and Regards,
samant
