As multiarch support is in gcc-4.8 you can compile with the standard gcc
sources and it'll work.

If you still want the debian patches for other reasons there's a
gcc-4.8-source package in debian testing and apt-get source gcc-4.8
might work as well. But it seems those packages are not yet in ubuntu?
