The problem only occurs when installing several toolchains from PPA or tarball since Ubuntu-provided toolchain have their own path. The solution would require to put the relevant files in a path specific to the toolchain being installed. Beside the work needed to do the change and test it, it makes the PPA a bit more different from our tarball release which is not a very desirable feature. You can avoid this issue by installing from tarball since this can be extracted into any directory.
