To produce a multilib toolchain, you need to build the C library as many times as you have items in this "with-multilib-list". However, as far as I understand Buildroot's code to generate toolchains, it only builds uClibc once. Did you actually check that this multilib thing was working ? > I hope this little doc will be usefull, and I'll be pleased to get feedback, I think it'd be great if we added a target/device/qemu directory, with target/device/qemu/sh4-rd2 as a sub-directory, containing your kernel configuration + a small README file saying how to run Qemu. Then, your Buildroot config file could be added to the configs/ directory. This ways, others could easily run this.
