So, you mean having this following change instead of make changes to
build.yaml and test.yaml, right?

    diff --git a/.gitlab-ci.yml b/.gitlab-ci.yml
    --- a/.gitlab-ci.yml
    +++ b/.gitlab-ci.yml
    @@ -14,7 +14,15 @@ stages:

Or I guess we can also compare to the string "true" and write the
expression as
    if: $XEN_CI_REBUILD_CONTAINERS == "true"
and
    if: $XEN_CI_REBUILD_CONTAINERS != "true"
