They are used as build tools for cross compilation. This import does not include the full distribution. Rather, it sports a shell script that will download and patch the distribution when compiled from /usr/src/tools (yet to be committed). This part of the source tree is only necessary for cross compilation. It's not used or compiled for native builds.
