This was previously used to force variants to rebuild every time the build was invoked. Now that the dependency tracking is more robust, this can be safely dropped so that images will only be rebuilt when one of their inputs has changed. Signed-off-by: Ben Cressey <[email protected]>
When building all variants, `cargo` will start many builds at once, which won't match up with the value in the environment variable. Instead, use CARGO_MANIFEST_DIR to determine which variant is being built. Parse that into its subcomponents at runtime to avoid needing any of the other variant-related environment variables.

Rather than failing the build for an unsupported architecture, emit a warning. Otherwise, building all variants would always fail if any variant definition did not support the requested architecture. Signed-off-by: Ben Cressey <[email protected]>
`buildsys` now parses the variant components on its own, and ignores these environment variables. Signed-off-by: Ben Cressey <[email protected]>
Previously, this functionality was in a separate binary because the environment variables needed to be set prior to `buildsys` invocation so that `cargo` could track them for change detection purposes. Now that packages can't be conditionally compiled based on the variant, change detection isn't required, so the binary can be removed. Signed-off-by: Ben Cressey <[email protected]>

Either this PR or #361 will need to rebase here. I have no problem doing so, and I think you have your approvals first!

This comment doesn't seem correct anymore, since we don't build host tools in Makefile.toml. Maybe we can just set CARGO_TARGET_DIR everywhere?

Maybe we can just set CARGO_TARGET_DIR everywhere?
Maybe, though there could be unexpected interactions with other uses of cargo, like cargo test in the unit tests task.
`buildsys` no longer depends on BUILDSYS_VARIANT, so it's OK to have a task that tells cargo to build everything in the workspace. Since various scripts might depend on the "latest" symlink created by the "build-variant" task, create the same links in the "build-all" task. Signed-off-by: Ben Cressey <[email protected]>

Description of changes:
This is a follow-up to #282 that removes the last of
buildsys's dependencies onBUILDSYS_VARIANTand friends. That in turn makes it possible to add a "build-all" target toMakefile.toml, which will help speed up CI runs.(Note that there's still no "publish-all" target;
pubsyscontinues to rely onBUILDSYS_VARIANTto know what to publish.)Testing done:
For x86_64:
And for aarch64:
