for every runtime dep of build we create a wheel and install it. This requires the build backends to be available already. We probably end up needing to add setuptools and flit here as well.

buildis a lightweight PEP 517 frontend for building wheels that couldreplace pip for this purpose.
installeris a new project for installing wheels.Why replace
pipwithbuildandinstaller?piphas a largecodebase doing many more things, and it vendors its dependencies.
See also https://github.com/FFY00/python-bootstrap
Might become significantly simpler if pypa/flit#511 is merged.
