Doh! That's what happens when you decide to rename something at the last minute.
Will fix, thanks.

No, un-necessary cleanup indeed. Will fix.

"make clean" might fail with the following error: make[2]: execvp: /bin/bash: Argument list too long This error was observed on a platform that has lots of additional source files compared to upstream (drivers, etc.), and that sets a long output path on the command line (make ... O=/some/long/path). Fix the error by splitting the file list into more manageable chunks. Note that removing one file at a time is not reasonable, because spawning too may shells takes quite a long time (up to 7-10 seconds to "make clean").
