Rust build system should be documented on the wiki.

I feel it would make everybody much more productive if the build system was well documented. The need for people to know more about it is clearly shown by people posting stuff like this http://www.reddit.com/r/rust/comments/1fz5xu/public_service_announcement_make_checkstage1std/ .

All the details of the build system should be well documented including how to build, test, and benchmark Rust at all stages.

There are wiki pages for this:
