It works around race conditions: when building in parallel, some gnu make versions look for a file's existence to determine that steps waiting on that file are good to go.

Poses to be a problem if these files aren't complete yet (but the process writing them takes a while). The diversion via .tmp has nothing to do with debuggability.
