tool: If make-usage.sh exits abnormally don't update the target file
- If make-usage.sh exits abnormally, the target output file is still
updated, and consequently subsequent invocations of make don't
rebuild the target. Store the output in a temporary file.
If (and only if) make-usage.sh exits without error, rename the
temporary file.
