In fact, relying on make clean for testing the build
system is a mistake.  It's easy for it to forget to
remove some temporary file. You really should do
a clean clone.

But testing is a completely separate issue IMO,
I'm not trying to fix that, just reduce the chance
of a failed or corrupted build.
