David Brown 0329c70036 scripts: Keep appending log between build parts
Instead of wiping the log file for each make target, only wipe it
initially, and then continue to append to it.  Instead of closing
between files, just flush.  Although the last use doesn't ever close
the file, it is flushed, and will be closed on exit.
