This PR is trying to fix issue #36956. The stage name is case-insensitive by design, so we should use `strings.EqualFold()` as the comparison method to eliminate the case sensitive noise. Also we need to return a pre-defined error code order to avoid below message like: "FIXME: Got an API for which error does not match any expected type!!!: failed to reach build target dev in Dockerfile" Signed-off-by: Dennis Chen <dennis.chen@arm.com> Upstream-commit: 7c0570473cfa181aeb3278072cc9af4f9298cb98 Component: engine
