Caused by the docs becoming much larger (~100 pages) due to numpy.poly enhancements.
…first. Occurs only on Python 3.x when a version.py file is already present, due to copying the whole tree into build/pyk3/. (backport of cd6d53f)

… 1.6.0 beta 1.
… ABI New Iterator - Read doc/neps/new-iterator-ufunc.rst. UFunc Update - Change all ufunc functions to use the new iterator. This replaces the inline buffering with iterator buffering, except for the reductions and generalized ufunc which use updateifcopy at the moment. Also adds out= and order= parameters to all ufuncs. Restore 1.5 ABI - This was done by moving the new type numbers to the end of the type enumeration, and replacing all type promotion code with a table-based approach. The ArrFuncs was restored by putting the new type cast functions into the cast dictionary, originally designed just for custom types.

This prevents importing non-2to3'ed numpy in Python 3 build, if numpy/version.py exists for some reason but .git does not (e.g building multiple Numpy versions from same source tree).
