For GSOC you should use rtems4.11. You will need to redo these steps to
build updated tools. You can find the current patches you will need to
apply in http://git.rtems.org/rtems-crossrpms.git/tree/patches

That will also give you hints about which versions of the tools to
download. The wiki instructions are somewhat outdated.

The path must be set before compiling gcc, or it won't find the binutils.
I'd be surprised that your gcc compile worked.
