Since wheel support was introduced in 2015 we always relied on pre-built wheels for bootstrapping. Now, we can bootstrap directly from the sources of these packages in git. The `bootstrapped-pip` packages is used to build `pip`, `setuptools` and `wheel`, after which those packages are used to build everything else. Note that when building `bootstrapped-pip` some errors are shown. These are not important, the build actually does succeed and work as intended.
