+1

It's so hard to achieve clean out-of-source builds when folks start 
doing in-source-builds... but this is important for maintaining build 
reproducibility. At the very least, if in-source builds are to be 
allowed, there ought to be a buildbot that complains when modifications 
to the source tree happen in out-of-source builds (and perhaps that 
ought to be something that we have anyway?).
