Note that, as Ryan and I found out in #45274, GNU Make (at least) doesn't sequentially run command-line goals to completion if it's told to operate in parallel. So there's no guarantee that the "clean" target will finish before the "all" target starts.

A somewhat uglier (but more reliable) fix would be to patch the makefile to make "clean" a dependency of "all".
