Bug 1455448: Don't include `firefox` in the decision task index; r=dustin,mshal,rail,Callek a=release The decision task is used for everything built as part of a push (for mozilla-central, this is firefox, devedition and fennec, as well as tasks that aren't strictly part of any product). Thus, having `firefox` encoded as part of the decision task doesn't make sense. This changes the route from index.gecko.v2.${repository.project}.latest.firefox.decision to index.gecko.v2.${repository.project}.latest.taskgraph.decision while leaving the latter for backwards compatability with tools that expect it.

# A traditional rule would look like this:
#    backend.%:
#        @echo do stuff
# But with -j<n>, and multiple items in BUILD_BACKEND_FILES, the command would
# run multiple times in parallel.
# "Fortunately", make has some weird semantics for pattern rules: if there are
# multiple targets in a pattern rule and each of them is matched at most once,
# the command will only run once. So:
#     backend%RecursiveMakeBackend backend%FasterMakeBackend:
#         @echo do stuff
#     backend: backend.RecursiveMakeBackend backend.FasterMakeBackend
# would only execute the command once.
# Credit where due:
$(subst .,%,$(BUILD_BACKEND_FILES)):
	@echo 'Build configuration changed. Regenerating backend.'
