Minor note, (traditional) RPM doesn't differentiate between the 'B' and the 'S'. 
  So build dir has historically be a combination of the two.

In this case, 'S' is likely better, because any additional post-processing is 
going to want to reference the generated objects and not the original source. 
(If the post processing needs the source, then globally S and B will need to be 
merged back together in a distribution specific configuration.)

So long story short, no objections.. just wanted to cover why S vs B makes sense 
here.
