Now that we require mach to run client.mk and mach only invokes client.mk for full builds (the "build" target) and configure (the "configure" target), we should no longer have anyone using client.mk as a proxy to make targets in the build backend. So remove that feature. MozReview-Commit-ID: BbaMdZHnRXy --HG-- extra : rebase_source : 570e81a62e35cbe4ea27e011883a306f23f3024c
