Well, I'll give it a spin myself in an empty directory.

It has been argued elsewhere, rather successfully that we need to
continue to support building in the source directory.

As gross and horrible as that sounds we need to avoid making changes
which break the ability to build in the source tree -- this is true
even if the recommended install procedures specify building in a
directory other than the source tree.
