You don't have to. The Pi 2 uses a much more common architecture and the ARM cross-compiler package in Ubuntu will work. See my comments here from yesterday for further explanation of that.

You should be able to find the package on Ubuntu with:

apt-cache search "cross-compiler" | grep -i arm

There may be more than one; you want the "hard float" version, probably called gcc-arm-linux-gnueabihf. This toolchain should then be in path, and the compiler will be called something like arm-linux-gnu-gcc; you may have get a clue from dpkg -l ______ | grep "*/bin/*" where blank is the name of the package (this lists some of the installed files).

Alternately, since ARMv7 is backward compatible, you should be able to use your old cross-compiler.
