It seems to me that this requirement is an error as it requests a 
specific solution to the problem rather than requesting a solution to 
the real problem.  It appears that the real goal is to have the ability 
to automatically check that a package properly cleans itself so that it 
does not cause various problems, just one if which is failure to build 
twice.  This request seems to be trying to treat the symptom instead of 
the disease.

If you verify that the clean rule restores the build directory to the 
exact state it was in before building, then the package will build 
cleanly a second time.
