Documentation+Meta: Remove references to nonexistent Toolchain directory

After b1d708dd16, the Toolchain directory
was removed from the repository. Some documentation and scripts still
referenced it, so this commit removes those references. The only
remaining references are in the gitignore file, to prevent bisections
from being polluted by the presence of a Toolchain directory in the
working copy.
