0) Binutils with --target=powerpc-linux. You may combine this with step
1 by creating a merged source tree, e.g. as described

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

If built separately then you need to install these before you continue.
They should be built with the same --prefix that you're going to
build/install GCC to.

or if you have access to powerpc-linux system headers and libraries (and
you're willing to use them rather than rebuilding glibc - probably a
good idea if you have an existing system in mind) then you can copy
these to <prefix>/powerpc-linux/sys-include and
<prefix>/powerpc-linux/lib and skip these two steps. This will be
described in the CrossGCC FAQ.

Good luck,
