Merge remote-tracking branch 'buildstream-tests/gnu-toolchain' into sam/buildstream-autoconvert

This branch contains a manual conversion of the Baserock bootstrap
process to BuildStream. The original branch can be found here:

  https://gitlab.com/BuildStream/buildstream-tests/tree/gnu-toolchain

It's not possible to automatically convert the existing Baserock
bootstrap due to differences in how BuildStream works.
