 Some people (e.g., me :-) use the same source directory to build several
configurations in separate output directories. In that case, building in the
source directory wouldn't work...

 If the package in question supports out-of-tree building (like e.g. the kernel
or most autotools-based packages), it would be possible that we don't copy the
sources but instead just build out-of-tree in the build directory. Thomas
Petazzoni posted a patch series to that effect about two and a half years ago,
but that series was incomplete and never got applied. So you could take it over,
perhaps improve and repost it. See [1], but mind [2]. Also, Thomas may have a
more recent version of the series.
