> 
> The buildclean task should call the package build system clean
> command, just implemented for Make for now.
> 
> This is meant for recipes where S == B, but can be useful as a
> standalone task for other recipes too.
> 
> Setting it to run before do_clean will do what most developers expect
> when calling bitbake -c clean.

Change "compile" to "clean" to avoid confusion.
