Yes indeed, and that one is good advice.

Not every Makefile out there is safe for -j > 1, so running it as one
job is valid debugging. It's the correct thing to do with weird build
failures as it tests if a specific condition is true or not.

Another example of proper debugging. A wise troubleshooter will first
verify that all relevant maintenance and consistency factors have been
done first before doing extensive troubleshooting.

The last one, "lafilefixer --justfixit" is especially valuable as it
gets right of a huge gigantic steaming pile of crap that a) should
never have been there at all in the first place and b) if it's causing
the problem is almost impossible to pin down without lots of work. So
even if b) is not true, you still get the huge benefit of a)
