Description

This technically fixes #1533, in that it’s now possible to run Buildstream with Nativelink. This has been done by doing the least possible implementation of the Remote Asset protocol that still passes the basic requirements of Buildstream i.e. Fetch always returns “not found” and Push throws away whatever it’s given. There’s also a few small config changes, because Buildstream needed an extra platform property.

I’m able to run a “hello world” Buildstream project based on the tutorial, but anything more substantial has not been tested, and so may well fail.
